Lightroom Classic crushes and closes by itself few minutes after opening

Hi everyone, 

So I'm facing the following issue. For the past few days my Lightroom Classic is absolutely unusable. Few days back I was editing a bunch of photos and then the whole thing crushed. When I restarted it all my progress was lost from the specific collection, however I could find the edited photo in the "past month" folder. 

After all it went downhill. Now everytime I open Lightroom and try do anything at all it closes by itself withing a few minutes (if that). 
I've tried restarting my iMac, even ran a recent upgrade to Sonoma, I've uninistalled and reinstalled Lightroom Classic, switched off the GPU function (saw someone recommending it for a similiar issue), but there have been absolutely zero results and I still can't work.

Any help and advice would be highly appreciated!
