RGB Curves Video Glitch

Hi!

I'm having a bit of a video-breaking issue with premiere pro. For some reason, I'm getting completely unusable video both in the timeline, and export whenever I try to use the RGB curves to adjust anything. Photos attached. One where it's completely white is when I'm scrolling through the timeline.

I uninstalled and reinstalled PP to no avail, and everything in my system is up to date.

When I change from CUDA rendering to standard, the issue no longer exists.

Please help!
