Hm... i had similar issue.
For chances if you go away from screen window for quite some time, when you return it will freeze for second or two (this part of image freezing IS normal as game reloads assets in VRAM which returns back from power saving mode (and no, sadly this is only power saving mode/feature i have no idea how to disable)) only after second or two of normal FPS (this part is NOT normal, it should load assets as soon as you return, not after second or two)?
I think you have same issue i had before. I don't know how specifically it got solved but what i have done before issue disappeared was
1) Windows clean boot (you can google this one) -->
2) Windows safe boot (you can google this one either) -->
3) AMD CleanUp Utility (run 2 times, first time you get warning as result, second one will be with green checkmark) --> Install 22.5.1 driver --> Boot into system --> Try run some games with browser video playback (it felt differently already at this point for me, almost no freezes when alt+tabbing quick and MUCH less sound stutters) -->
4) Boot into safe mode again -->
5) AMD CleanUp Utility (x2 again) -->
6) Install 22.10.3 (i installed 22.10.2, and if you still have one you can start from there) -->
7) Boot into system again.
After i done this issue with frequent system freezes leading to driver crash or game/system lockdown and sound stutter was gone. More than that, despite issues above persisting through MULTIPLE versions of drivers as if they were HW related, they are now permanently gone.
There are still remains of problems, though, such as:
1) random (but at this point VERY RARE) sound stutters when alt-tab at load intensive moment (f*** MPO)
2) Game having frame "freeze" for asset loading (1-2 seconds) when i unfold it after neglecting for a while is normal. But sometimes, now rarely after resolving main problem it still appears as issue (look at 2.1)
2.1) Sometimes (rarely) VRAM feels wonky and it just doesn't ramp frequency up, making asset loading much longer. Can be resolved by alt-tabbing again or using some system interface like sound increase from keyboard (to make something overlay on top). Basically still same as you described, but it hadn't yet frozen my system completely or reset my driver as issue i had before.
To be fair at some point i felt like frequency increased, but after installing 22.10.3 i hadn't felt this again? (If you ever feel same reinstall driver?).
Anyways since i done that and used 22.10.2 and 22.10.3 i had no system lockdowns or driver crashes, yay. So i hope this will help you as well
