Can you test 5.11-rc to see if this issue is there as well?
Tested with 5.11.0-rc2 and 5600 XT, same issue.
"xset dpms force off" turns the display off and it won't come back, with the same error in the syslog.

Can be worked around by
1) turning display power off completely 2) switching to console 3) turning display power on - linux console shows up 4) switching back to X
