Serious backend problem opening projects or importing assets on Fedora 35
A while ago I used Pitivi to edit some videos, everything worked flawlessly. Now I wanted to edit those projects back again and I realised I cannot use the program at all. It isn't just related to those projects as opening a new project and importing any assets (tried mainly with mp4 videos and pictures) triggers the same error. The terminal output is as follows:

On the GUI in both cases there's the following window, where pressing any of the buttons hangs the program (I need to force quit it).
I have no idea what is going on, but I'd be happy to provide more information if required. Thanks in advance
