This is surely the OBS Browser crash (can be docked pane too). But that is all. Here the "Unhandled exception: 80000003" is more likely "Not enough resources to complete the task" (it's my own opinion, that summarizes all thoughts about the question "why the program thread was terminated, so early?").
The most in-deep analysis and detailed steps taken to resolve the issue was in this thread on the forum:
https://obsproject.com/forum/thread...acceleration-enabled-on-fresh-windows.196188/
and half of the steps you already did (disabled hardware acceleration for the OBS Browser source).
Why clearing temp files triggered the problem? I think, it is just coincidence. The problem is different. But make sure that the trash bin is empty and your system disk has enough free space to Browser source to work normally.
