OBS won't start


New Member
Few days ago I installed OBS studio (26.1.1 newest version) from official repository (repository ppa:obsproject/obs-studio). After a few minutes of playing around it just froze, crashed and won't start again. Clicking on it does nothing and opening it in terminal gives this:

After removing (sudo apt-get remove --auto-remove obs-studio), I tried to reinstall it, checked and messed around with nvidia drivers. Didn't help, it won't start. I started using linux a month ago so still trying the sort it out. How can I find out what's wrong?

I installed it as flatpak (v26.1.1) from Software Manager in LM20 (in my case) and works flawlessly so I suspect the issue was in my system, but haven't figured out yet what it might be.
