Libreoffice does not start: Application Error

I am not able to start libreoffice. Linux Mint 20.1
When I try to start the applications via a command line, the application stops (and never opens) with the cryptic message “application error”.
Libreoffice had worked very well before.
I have tried completely purging and the reinstalling, and nothing changed.
Application also does not open when clicking on a file.
Version LibreOffice 7.1.6.2 10(Build:2)
