How do I recover the last saved session?

[Bri-Toon]

There is some very strange bug that occurred. I kept saving my work, and then later on I got a popup of another unhandled file extension causing the program to crash. So I reopened my file to continue working, and I saw that I lost work I already saved. If I kept saving, then why would I not be able to view the last overwritten version? I do not want to do anything more just yet for in case I make anything worse. Please, is there a way to recover what disappeared?

Does it prompt you to load a recovery file when you restarted? Or did you manually load the file?

It didn't last night when I reopened it, but when I reopened the file today, it did prompt me to load a recovery. Plus, there was a new file on my desktop that wasn't there last night. It was a more complete version of my drawing. That is very strange but one heck of a relief.

 

But the program did crash twice last night, so it might certainly crash again. As far as I can tell, there was no pattern of what triggered it. I can however say my computer keeps revving up, and I have previously installed dozens of programs this year (not all installed now). I think you were right when you said there might be a problem with my graphics card, but I'm not sure how to fix it. The other computer specs like CPU and memory are fine.
