I've solved it, just don't remember how
It crashes after first screenshot/OCR, yet is enough like this :: if I want a 2nd OCR I open again the app
I needed to install a library, and after I've installed it I got a message on the first run asking for "capturing screen" permission
I'm on Ubuntu 24.04 with the same debug information. The Appimage works though.
AppImage wasn't working when I had flatpak installed as well. I removed both and then downloaded AppImage again. it's working now.
NixOS user here, with the same issue:

Did you provide the permission to take screenshots?
It doesn't ask for it:
On the first screen it's only "notifications" and "run in background", on the second one - "network access"
I see people still with problems, for me now is working :: Only I've done is keep updating my system.
It doesn't ask for it:
Strange. Reinstall it and it should ask you for the permission on the first start, at least it was the case for me on Ubuntu + Flatpak version.

I literally just installed it today to make those screenshots, because it was uninstalled when I've discovered that it's not working:)
Can you try granting the permissions manuall?
For Flatpak you can do this with:
flatpak permission-set screenshot screenshot com.github.dynobo.normcap yes
For AppImage on most Wayland systems you can do this with:
dbus-send --print-reply=literal \
--session --dest=org.freedesktop.impl.portal.PermissionStore \
/org/freedesktop/impl/portal/PermissionStore \
org.freedesktop.impl.portal.PermissionStore.SetPermission \
string:'screenshot' boolean:true string:'screenshot' \
string:'com.github.dynobo.normcap' array:string:['yes']
If you are interested in more information about the unfortunate situation regarding screenshot permissions (and debugging tipps), please read this FAQ.
Can you try granting the permissions manuall?
do you think it's the proper way how the app should be working on the user-side?

Definitely not! As explained in the linked FAQ, I'm totally aware of the issues with Wayland, it's just very hard to do right, especially with limited resources as an open source project.
Nevertheless, I always strive for improvement, and also welcome any contribution. Even feedback like yours is really valuable!

Could you please try again with the new v0.6.0 release? It includes some changes, which should help with automatically requesting the screenshot permissions, at least on some systems.
