Yep, this is a well-known problem with anything newer than 0.6-203 (except partially for 0.6-206 which fixed the 5700 issues but causes Radeon VII cards to drop 2-3MH/s).
Just stick with 203. Stable on my 5700 rig for 5+ days, R7 rig hashes at 108 instead of 106, and my ampere/turing rig’s invalid shares increase tenfold on anything newer than 203.
I had the same issue on a previous update. I’m still running 5.4.80 / 0.6-203@210608 given the problems that occurred when I upgraded. A number of other people had similar issues, see my post here: 5700 xt rigs crashing on 5.4.80
