Material Shelf Will not load past the letter G. and it keeps freezing my PC!

It is exactly as it says. I am trying to load my material shelf, and it will only load the materials that start with a number to the ones that start with the letter F. Others will not load, and it is extremely frustrating. I do not know what is wrong. The program also will not close properly; I have to go to ask the manager to close the program, which I have never had to do before, but its freezing my PC a lot. Can someone help me figure out why Substance Painter broke and how I can get my library to load? It constantly is saying generating thumbnails, but nothing; I have uninstalled and reinstalled everything.

I have my local cache at 3000, and my Specs are a 3900x and an RTX 4090, running substance from an SSD
