photoshop killing itself for no reason

I was editing a picture in Photoshop, and it was going completely normally. Then I went to Quick Export as PNG, and when I pressed it, it said, "Can no longer use GPU, so will use CPU to export. You can re-enable GPU acceleration in Preferences." So i pressed ok then, I went to Preferences, and Use GPU is still checked, so I unchecked it and re-checked it, and then I pressed OK. And then Photoshop gave me an error saying, We're unable to complete this action due to an error, and it didn't say what the error was or anything. And then I checked my desktop where I was exporting it to, and it just exported the base image, like, the background image that I started with, with none of the edits to it or anything. And it didn't even have the name I gave it when I pressed Export, it just had the normal name it started with. And the preview in Photoshop just randomly went black after closing preferences, and then I tried to save the project so I don't lose it and when I pressed Save, it says, We're unable to do this due to an error it didn't give me an error code or anything, it just said, We're unable to do this because of an error. And then, I couldn't figure out why and couldn't get it to work. so I went to Task Manager and checked, and my CPU, disk and everything were completely normal, but my memory was at, like, 97%. But it said Photoshop was only using, like, 600 mb, and there was nothing else running other than photoshop, chrome, task manager and my anti virus all taking up normal amounts and nothing else was using any memory, so I was very confused, i still had 25gb free on my disk and 75gb left on my computer. I also tried to purge all so i could clear my cache and stuff but it said unable to complete this action for no reason And then I ended up just force-closing it using End Task. then my memory usage dropped to like 40% which is pretty normal and then I decided to restart my computer, just in case something else was going on in the background. And then when I restarted my computer and opened Photoshop, it said, Unable to read device-specific preferences. So will go back to Default, and then I just pressed OK, and it reset all my preferences. Then it also reset my recent files and everything weren't in Photoshop. So I had to go to where I keep my files on my computer, and I opened a random file, and it was completely normal. It asked me if I wanted to add a new tool to the toolbar or not, and I said, Sure, reset the toolbar to Default, and add the new tool. then it did that, and it was fine. And then I was just hovering over the tools on the bar. I didn't click on anything. I was just hovering over them to like see what the name of the tool was and what it did. And then it randomly just said, Photoshop encountered an error and needs to close, and didn't tell me why or give me an error code or anything. then i tried to reopen it and it said the same thing about not finding prefernces but didnt crash this time. So my Photoshop's basically broken for no reason.  I have 16 gigabytes of RAM, and graphics card is a rtx4050 also my graphics card and Photoshop are both fully updated. I wasnt even doing heavy editing just had a couple masks and only like 5 layers that were all just masks of different images. please help.
