laptop overheats and generally works bad after AMD drivers upgrade

ASUS TUF Gaming A15 FA507NV-LP031. I've recently had a problem when my laptop wont use dGPU at all. After some futile attempts I managed to fix the issue by updating CPU and iGPU drivers using AMD software adrenalin edition, and first it seemed to work, but then I noticed where previously I've had no problems during gaming, now the games sometimes will crash and lag in more intense moments or just on a whim (never happened before). To add to that, it definitely shouldn't heat to up to 90 degrees Celsius while I'm writing in MC Word or leaving it on a sleep mode with nothing running.

Before new drivers there was something like a default windows driver for iGPU but I'm not sure where to get one or will it fix the issue. NVIDIA software is also I believe not to be blamed as it was on my PC long before all this happened. Asus support wasn't of any help. Recently I deleted some of that AMD bloatware and it helped a bit but still did not fix basically anything. I can play Deep Rock Galactic but can't watch videos on youtube and my battery drains like crazy even in power saving mode. I'm desperate enough at this point that I'm willing to tip 10$ if your advice works and it isn't like "do a clean reinstall". Thanks in advance.
