Additional info
Works well with the App Image.
Can you share the client logs when trying to open the window? The client writes the logs to ~/.config/Nextcloud/logs, the most recent one should contain them (keep an eye out for messages that contain qml)
@nilsding Hello I've the exact same problem in Linux Mint 22.2 Zara base: Ubuntu 24.04 noble
My log with the qml extract says :

Thanks a lot
My logs with qml are :

@webafrancois thanks for the logs, I see what's happening there
the popupType property was added to Qt 6.8, which is much newer than what's available in the Mint/Ubuntu 24.04 repos. The AppImage includes a newer build of Qt which explains why that one's working fine.
I can confirm breakage on xUbuntu 24.04.3, qt-version is 6.4.2 ... hope there is a way to get it fixed (we had this before when changing to client-version 3.0.0).
Confirm same issue with 4.0.1 Flatpak (com.nextcloud.desktopclient.nextcloud) on Linux Mint 21.3 (Ubuntu 22.04)
Also Pop!-OS 22.04 with flatpak 4.0.1not working anymore.
Did strace flatpak run com.nextcloud.desktopclient.nextcloud
At end of messages seem to be some interesting things:

p.s I also upgraded to Nextcloud 32.0.1 this morning, did not have a need to open flatpak 4.0.1 before this. I am not sure flatpak 4.0.1 was working before this Nextcloud update. Wanted to check syncing problems after upgrade of Nextcloud because the upgrade to Nextcloud 32.0.1 gave me a some problems ... Nextcloud lied when stated that all apps having compatibility ...
@gav- @DeRaafMedia as this issue is concerning about the PPA package (and the cause has been identified), could either of you please create a separate issue about the Flatpak that includes the following information?
- What desktop environment are you using?
- What GPU (and driver) do you use?
- Which runtimes are installed? (
flatpak list --runtime) - Does running the AppImage work?
- Does right-clicking on the icon to open the Settings window work?
- Is there any other Nextcloud process running? (
ps -ef | grep -i nextcl)

I believe it's a bug in the source code that basically affects all builds not just ppa.

I would agree with this.
@melroy89 from my understanding the Flatpak is supposed to be the very same for each distribution, especially as it's using its own runtimes separate from what is provided by the system repositories. This issue is all about the packages in the PPA trying to use newer Qt features which are not available on systems that aren't on Qt >= 6.8 yet.
fwiw I just tested the 4.0.1 flatpak on two machines again: one with openSUSE using an AMD GPU, and the other one with Fedora using an Intel GPU. Both of those setups are on the KDE desktop though, so this might have some influence on the specific Flatpak case.

I have read I believe 3 threads that seem to describe the same bug symptoms ... three threads for three separate systems (saw a window thread, two Linux threads). You just changed the title of this thread to include this is for PPA installs ...
In my opinion you make things overcomplicated for yourself treating this bug different for many systems and install methods. I think it would be more helpful (to yourself and others) to combine these threads instead of splitting them up even further in "sub" bugs. But again that is just my opinion ...
What I would be curious about, @rihards-simanovics said 25.04 is also affected which ships qt 6.8.3, it should work with this version, no? Up to date version is 6.9.2, which is shipped in 25.10 fio example. It would be interesting if this one is affected too, before thinking about general bug, that I don't see till now (as said before, same problem with qt version was when updating to 3.0.0).

The Flathub Flatpak package is relying on the 6.9 branch of the KDE runtime, which is currently at Qt v6.9.3:
https://github.com/flathub/com.nextcloud.desktopclient.nextcloud/blob/867d70b4fcc79f5b36f33ff5171186b86d59e93c/com.nextcloud.desktopclient.nextcloud.yml#L4

Since I was mentioned, and the comment hidden tag was removed, I would like to clarify my system specs below in case they are helpful. I think the most relevant would be that I use Wayland, and the Nexcloud desktop client originates from Flathub, the system, as you already know, is Ubuntu 25.04.
I am planning to install 25.10 today in a VM to test out the software I have to see if I can upgrade and I will test out the desktop client as well.

Updating as promised, Ubuntu 25.10 is not affected. So, as zefr0x and others mentioned, it must be version incompatibility. What surprises me, though, is that (seemingly) no one has tested the update on different distributions.
Hello github readers, same behaviour with LUbuntu (running LTQX - xcb - sddm) (similar to Linux Mint)

tell me if you need debug logs, i HAVE capacities to help you
no one has tested the update on different distributions
that IS normal
and second how to raise log level for the nextcloud client, the click on "Open Nextcloud Desktop" does not produce any log entry in the client logs, not even if you click "Settings" from the nextcloud desktop tray menu
Hello, I'd like to know whether there is a way to solve this issue in Ubuntu 24.04. If there is a library that must be compiled, is there anyone to give some guidance on the version and documentation of such library?
If I'm not wrong, AppImage is not a full replacement for the PPA installation as it doesn't offer File Manager integration (Nautilus in my case)?
Does someone know which version of nextcloud-client started to have the issue, so one could roll-back to an working version?
Does someone know which version of nextcloud-client started to have the issue, so one could roll-back to an working version?
4.0.0, last working version was v3.17.3 for me
Does anyone know how to downgrade back to 3.17 on Ubuntu 24.04? Nextcloud desktop ppa does not have previous versions.
Found this, hope it works ... https://help.nextcloud.com/t/how-to-downgrade-desktop-client-back-to-3-17-3/234508/2
Just tested it, it works as afollows. Download the corresponding files (change regarding architecture/file-manager):
caja-nextcloud_3.17.3-20251010.150706.392da9a259-1.0~noble1_all.deb libnextcloudsync0_3.17.3-20251010.150706.392da9a259-1.0~noble1_amd64.deb nextcloud-desktop_3.17.3-20251010.150706.392da9a259-1.0~noble1_amd64.deb
Install all files together:
sudo dpkg -i caja-nextcloud_3.17.3-20251010.150706.392da9a259-1.0~noble1_all.deb libnextcloudsync0_3.17.3-20251010.150706.392da9a259-1.0~noble1_amd64.deb nextcloud-desktop_3.17.3-20251010.150706.392da9a259-1.0~noble1_amd64.deb
Restart nextcloud-client.
Hold the corresponding packages:
sudo apt-mark hold nextcloud-desktop caja-nextcloud libnextcloudsync0
Updating as promised, Ubuntu 25.10 is not affected.
ok, I'm not sure what the problem is. I've upgraded my os from Ubuntu 25.04 to 25.10 on my actual workstation, and the issue persists. It must be something with the runtime or the environment. See the printout of the flatpak runtimes (apologies, I've got quite a few apps, so there are quite a few runtimes)

Tried upgrading to the "beta" and "alpha" packages from the PPA, no change whatsoever. Sent a message for the responsible team via Launchpad, let's see what happens.
