Hello,
Facing the exactly same issue with Opera Developper.
Version:92.0.4540.0 (arm64)
Opera is up to date
Update stream:developer
System:macOS Version 12.6 (Build 21G115) 12.6.0 arm64
Chromium version:106.0.5216.6
I could remove the AD Block and turn the restricted mode for a while, but then it came back.
