But I'll tell you the things I've tried personally, some of which might help according to other posts on the web, but they also might not help in your specific case. I've searched quite a bit for solutions to this and it's really mostly voodoo stuff. I've never been able to completely solve the issue, so it still occurs, but it occurs very rarely now so that I can tolerate it.

I've had this kind of problem for a long time with 2 different PCs and AMD GPUs (the older one was Zen1 based with a Vega 64 and the new one is Zen3 based with a RX 5700 XT).
