While trying to start LibreOffice Writer (Ubuntu 22.04.4) in GUI (Plasma, sddm) - it is not opening. Recently installed 6.8.0-40-generic kernel, installed nvidia drivers 560.35 and experimented with display composition (not sure if it could be connected with this issue).
Tried to launch from console - getting error ERROR 4 forking process.
As a workaround I found that this shortcut: /usr/lib/libreoffice/program/soffice.bin
seems to work (open LibreOffice window).
No other solution worked - tried to reinstall (no resolution), adding some paths, installing/reinstalling xapp - did no solve this issue.
.
No solution, but the same here:
