Photoshop 21.1.2 Zoom and Pan Freeze

I'm running into a problem where zooming and panning via the hand tool's spacebar shortcut seems to freeze up everything but the navigation bar at the top of Photoshop on Windows 10. 

It doesn't happen every time I use spacebar to quickly access the hand tool and pan, but once it does, Photoshop is nearly non-responsive. Luckily, I can still save my document, but that's about it. The view will be frozen, my default system cursor takes over so I'm unable to see the tool-specific cursors, and none of the tools are able to be actually selected. It's like everything besides the top menu is completely frozen, like I'm staring at a screenshot of the Photoshop I was just working on as opposed to running the actual program. I originally wondered if going into fullscreen mode would help, but it didn't seem to work at all.

It should be noted that I've replicated this issue with a mouse, since I originally thought this was an issue with my pen tablet display. I actually spent a couple days uninstalling both Photoshop and my tablet drivers and starting from scratch - down to removing excess files by hand. I've also run through some cursory troubleshooting steps, given Photoshop more access to RAM, and switched over to legacy compositing to see if it'd help. Nothing, so far.

Currently, my temporary fix is to save the file and completely restart Photoshop. I had originally been closing the file but not Photoshop, and just reloading the piece, but it seems like the error occurred more frequently with this fix as opposed to completely closing and starting up again. The error feels random, so I can't verify that this is the case, however. Quitting works for a short while, obviously, but it's impossible to tell when you're going to have to do so again, and doing this dozens of times within a couple hours is really starting to drag.

I'd love to find a fix! The spacebar zoom and pan is SUCH a huge part of my workflow when painting and photo-editing. I absolutely love it and don't want to have to live without it!
