Blender slows down after using for a while forcing me to restart

Hello, I’ve been having a problem with blender for a while now and I have no idea what’s wrong. I open a scene start working on it and after a few minutes the program slows to a crawl. I have to restart blender and then reopen the file for the performance to go back to normal. Someone suggested that I upgrade my ram which is what I did I upgraded it from 8GB to 20GB. but I’m still having the same issue here are my specs help would be greatly appreciated
