Frequent crashing started recently

Yesterday, after working in Illustrator for a few hours, the program began to crash frequently. I was prompted to send the error report to Adobe then the program closed itself. This would happen every 10-15 minutes, but as the day went on, it became more frequent. Now, I can maybe work for about 10 minutes before it crashes, but many times it will crash right after opening the program and before a file is loaded. The error report says it’s an unknown exception and does not really help.

I am on version 29.7.1 and cannot upgrade because I’m in a professional environment where every computer needs to stay on the same version of the program. I haven’t made any changes to my PC or installed any new software. Graphics drivers are up to date and have been uninstalled/reinstalled. I have reinstalled Illustrator and Acrobat with no success. Does anyone know what may be happening?
