I'm on 20.12.1 and been mining for the last couple months just fine.
21.3.1 and 21.3.2 are NOT compatible and have problems with Phoenix at the moment. The next version is going to fix it, but no information has been given on the version number or when it will be released.
To be honest, 21.1.x was the last really good version. 21.2.1 crashed a LOT when trying to mine and web browse at the same time with my Radeon 6800(non-XT), 21.2.2 and 21.2.3 helped, but still had the occasional driver not responding and recovery(I am using 21.2.3 but performance is down a touch compared to the 21.1 series).
Thank you I will try some of those drivers and hopefully fix the crashing.
