Frozen Loading Bar

(Sorry my bad English, still learning...)
I'm having the problem that the loading bar is stuck at about 30-40% of the way when I try to open a project, I've left it open for about 2 plus hours and the loading bar dont move at all

Things i tried: reinstalled Windows 10, cleaned my PC, updated all drivers...
I really don't know what to do and I'm very frustrated because I can't work.

PC:
Ryzen 7 5800x3d
32 GB RAM
RTX 3080

The program simply doesn't consume RAM, cpu or disk or other resources, it just makes my GPU go to 100% 

I have the most current drivers for my GPU

Most current version of the program

Project is less than 200MB in size

​Any tips or suggestions i could do?
