I've got the same problem here.
ASUS TUF Gaming A15
AMD Ryzen 7 5800H
Geforce RTX 3060
I keep getting infrequent black screens - the issue is accelerated whenever someone is screensharing. Interestingly, it seems to happen more when people screen share with me rather than when I do it myself.
Can someone sort this out? I've already reinstalled the drivers and done a clean install. This is clearly an exsiting software bug. AMD needs to take their eye off games for a second and realise people also use their products for work and that it needs to be compatible with the WORLD'S MOST USED VIDEO-CONFERENCING PROGRAM.
