Main window does not open (Debian Trixie, KDE, v33.0.0)

[schlimmchen]

The client in version 33.0.0 seems to work fine, except that the "main window" can't be opened. This is the window I mean:

Using "Open Nextcloud Desktop" from the system tray icon's context menu (right mouse button click) does not work either.

This worked fine in 4.0.8 and it also works when using the AppImage version 33.0.0, which is why I create the issue here. It seems to be flatpak-specific in some way.

This is what I see on the terminal when starting the flatpak app from there:

$ flatpak run com.nextcloud.desktopclient.nextcloud

Same issue on Fedora 43

Issue persists in Version 33.0.1.
Is there anybody who can fix this?

[nilsding]

could you try the workaround of cleaning the qmlcache from a previous issue? #218 (comment)

i.e. deleting ~/.var/app/com.nextcloud.desktopclient.nextcloud/cache/Nextcloud/qmlcache

Yes, this solved the problem. Thanks a lot!
Just wonder, why this problem is not addressed...

Thanks for looking at this. The workaround also works for me. Can the app itself know that this cache needs to be purged and do it?

[narFnarF]

I had the same issue. The proposed workaround seems to have worked for me too.

deleting ~/.var/app/com.nextcloud.desktopclient.nextcloud/cache/Nextcloud/qmlcache
