After installing graphics driver my computer screen freezes

At the end of the installation process, you are supposed to restart the notebook. After booting back up it seemed totally normal, but for some reason after logging in through windows hello the IR LEDs next to webcam stopped shining but the screen remained frozen at the same login gate but my external monitor connected through USB-C showed the desktop bu the other one remained frozen. I then restarted the computer a couple of times again to see if that would help. but it did nothing. Then I switched to only the external monitor trough keyboard shortcuts and installed the AMD driver again, but it seems to not have worked again because the problem remains. Although this time the screen refreshes every like 15-30 seconds if I mirror the view from my external monitor to the notebook monitor. But this may have happened before but I haven't tried the mirroring thing before the second installation...

I also noticed that the USB accessories I had connected trough my USB-C hub don't seem to be recognised by the computer but if I connect them a straight through to the computer it recognizes them straight away.

After updating BIOS and uninstalling all the drivers and then Installing not the latest drivers that HP makes, because it says that the newest ones (v1903) don't support my OS version even though I have the newest version of Windows. I had to install the 1803 version even though I am running win 1909 which came trough with no errors but the computer still said that there are no graphic drivers and I had an old installation of AMD adrenalin software from late 2019 which I installed and for now it seems to be working.

But I am still curious about the error while installing the drivers. It said exactly this :

WARNING

"The driver is not supported on this OS version (10.0.18363)"

I was installing trough the hp install assistant. And the notebook model is13-ag0010nc.
