bake bug

Guys, I'm having this problem with the bake in my Substance Painter. I bought the Steam version. The program was working normally, but now it’s like this: every bake I do has this issue. Either it only loads halfway, or when it finishes the bake it stays on a screen that looks like it’s endlessly loading. And when I try to leave the bake tab, the program glitches with one window overlapping another. I’ve already tried everything the support recommended, and nothing worked. Does anyone know what it could be?”
