[UPDATE] A driver uninstall and reinstall fixed this issue, that hasn't work in 15 years for me! Anyway, back to not trusting updaters I guess, one update and broken 
I play Guild Wars 2 almost daily, including yesterday before I installed latest driver. Now GW2 won't launch, I cant even get to the launcher it immediately crashes on click. Possibly related but I don't know because I didn't try to play it until today, I got Life is Strange on Steam, won't launch, instant crash. Guess I'll hold off on Life is Strange 2...I played War of Rights, a game in Alpha, runs fine. Any ideas?
This is a brand new system:
Gigabyte Pro WiFi, latest bios
Sapphire Radeon 5700, 19.7.2
AMD 3600x
16GB ram
Windows 10 Pro, up to date and full virus scan, install is 1 week old
No overclocks
