Windows April Update messed up my GPU driver hardcore

I'm running Windows 10 x64 with an RX 580 and my PC auto installed the April 1804 update. After updating my dual monitors were duplicated (instead of extended) so I checked things out and found that in Device Manager my GPU says "Windows has stopped this device because it has reported problems. (Code 43)"

After a bit of troubleshooting I decided to do a system restore to a time prior to the update, but that made things worse and I was getting a BSOD at boot ("Stop code: BAD_SYSTEM_CONFIG_INFO"). After messing with it for a bit with no success I decided to restore back to the post-April update state and that at least got me back into the OS, but my GPU is still hosed...

I've tried uninstalling drivers with DDU, reinstalling the 18.4.1 Radeon drivers (also tried the same with the 18.3.3 drivers), but I'm still getting code 43. I'm totally at a loss. Anyone have any ideas? Thanks in advance!

 

Do you know what gpu driver you had installed when it was working? If so have you tried reinstalling that version? I would also try 18.2.1 and the minimal driver.
