I understand what you are saying, but drivers created before the 5600 series GPU cards came out may not be completely compatible with the RX5600 series GPU cards. Thus the issues you are having.
After the RX5600 officially came out, then AMD started making all drivers compatible with the new GPU card.
If you means the version after 20.1.1, I already tried it all of them. I think the previous mean version 19. My point is I want to use version 19 instead of buggy version 20.
Not a solution, but a workaround - have you tried to CTRL+WIN+SHIFT+B shortcut to restart drivers in Windows when getting a black screen?
Another possible workaround - disable hardware acceleration in your browsers.
Specifically this page:
I know 5600XT is not on the supported list but it is likely that 5600XT Professional versions of the GPU will be made available.
So maybe you can ask for Radeon 5600XT support in the Radeon Pro Software for Enterprise 2020 20.Q2 Software.
First step for you to try please.
Download DDU: Official Display Driver Uninstaller DDU Download
Download Radeon Pro Software for Enterprise 2020 20.Q1: https://www.amd.com/en/support/kb/release-notes/rn-pro-win-20-q1-1
Remove connection to internet. Boot into safe mode. Run DDU toi Remove Adrenalin 2020. Boot into Windows normal mode still disconnected. Run the Adrenalin 2020 20.Q1 installer.
Please let me know if it installs.
If it does not install you will have to open a support case to get it to install.
It might be an easy fix for AMD, just add your GPU to an installation whitelist.
That should get you into a position where you have the Adrenalin 2019 Style GUI and Enterprise drivers for your GPU.
