Detailed Description

on Discord I got an attempt to help:

Looks related to this https://codereview.qt-project.org/c/qt/qtbase/+/538064/2
or whatever target you are running it on doesn't have/support zstd

but the solution is not clear to me, it does not specify where/how to add QT_NO_AUTORCC_ZSTD

Did you install libzstd-dev?

[AndKe]

yes, and I verified right now in case that was a new dependency.

libzstd-dev is already the newest version (1.5.5+dfsg2-2build1).

[HTRamsey]

try creating the appimage

[AndKe]

creating the appimage? / did you mean it, how?

What I have to do on my master build on Kubuntu (Ubuntu flavour) 22.04 is: Right click on the build file instead of directly running it. Then select "Run in Konsole" It will fail initially with some warning message. Then I repeat this and it will run fine. ( I believe a background service isn't running at first startup but is ready by the time you start again)

I discovered update build instructions, and it works. :)
