Can't open files except from LO panel

Hi, I can only open files inside LO panel. If I try to open any file from my distribution’s file manager, LO starts, keeps running, but shows no document at all. No errors displayed. I’ve checked my running processes and it’s active, and there’s no other instance running.

I’m using Endeavour OS with KDE. All updates installed. My LO version is LibreOffice 7.4.1.2 40(Build:2), but it started with a previous version.

Running journalctl -f when I try to open a file shows:

oct 11 17:22:06 lptop systemd[797]: Started LibreOffice Writer - Word Processor.
oct 11 17:22:07 lptop kwin_x11[849]: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 20844, resource id: 56623105, major code: 15 (QueryTree), minor code: 0
oct 11 17:22:07 lptop kwin_x11[849]: kwin_core: XCB error: 152 (BadDamage), sequence: 20892, resource id: 16785318, major code: 143 (DAMAGE), minor code: 3 (Subtract)

I’ve also tried with a new profile, but only managed to open just one file. Afterwards, same problem.

Is there anything else I can do? Need more information about the issue?

Thanks in advance.
