A lot of Photoshop issues

For the past 2 months atleast I've been having really annoying issues with Photoshop.

The main issue I'm having is when Photoshop does this thing where... the screen is not frozen, but I'm unable to zoom in or out, or click any buttons, forcing me to close the program, losing anything that I didn't save. Think it's some kind of visual error, because it seems like the program is still operational, and happens at random points in time when I zoom in and out.

The second and third issues I'm able to screenshot, my export screen is blank, even when I close and reopen Photoshop. The third issue is an error message I get when I try to save.

To sum it up, the program is screwing me over, and I've wasted hours of time because of this issues, any help would be great.

Thanks,
