Nope, no solution or fix.
You can turn-off "Show my taskbar on all displays" to prevent it from happening at all, or start doing hacky **** to try to counteract what's setting off this bug. Her are a couple of things I have experienced to work most/some of the time:
- Disable display overlays from manufacturers like Nvidia.
- After awakening from sleep (and seeing the error), lock your screen and then unlock it again.
For the record, I gave up on dealing with it and turned-off "Show my taskbar on all displays". The Windows 11 GUI is very buggy - particularly in relation to dual monitor setups.
