Frozen Loading Bar

I’m creating a new post about this topic because everywhere I see theres no solution. I can open the file, and I can export texture, but I’m not allowed to modify it since if I do anything it starts to load and never finish, ending up to be closed by ctrl alt del. I’ve seen in way too many posts, for some years ans this bug is still nowadays all strong. Whats the problem with this software? its a industry standard going with the same bug FOR YEARS. This is just ridiculous
