Exactly the same problem. I think the only relevant info on hardware is: 1) Ryzen 3 2200G, 2) ASRock AB350M pro4 motherboard. I use Win 10 Pro.
Latest UEFI (BIOS) updated.
I've tried several drivers packs:
AMD: rv-win10-64bit-whql-radeon-software-17.40.3701-feb12
AMD: radeon-software-adrenalin-18.6.1-minimalsetup-180613_web
AMD: win10-64bit-radeon-software-adrenalin-edition-18.5.1-may23
ASRock (MB manufacturer) drivers pack: Allin1(v17.40.3301-WHQL)
I've tried uninstalling VGA drivers, then I get plain "microsoft generic driver"
Then I install AMD drivers back and I get the same yellow triangle when I check Device Manager: "Display Adapters"...
Device status:
This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system.
