I am currently running 64-bit Windows 11 Home Version 21H2 (OS Build 22000.100 co_release). Upon setting one of my two monitors to portrait, explorer.exe keeps restarting while said monitor is plugged in. Unplugging it temporarily resolves the issue, however it resumes when it is plugged back in. Both monitors are plugged into the gpu via display port. Power cycling the monitor in question has not proved fruitful. Prior to the most recent update, this was not an issue for me. Restarting my system has also failed to resolve my issue. I am currently out of ideas on how to solve this.
