I certainly understand your concern.

To diagnose whether this issue occurs in “Safe Mode”, let’s reboot the computer in safe mode and check if the issue appears there as well.
Safe mode is a diagnostic mode for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. This helps us in identifying whether the issue is due to some third party programs conflict. The word Safe mode appear in the concern of your monitor to identify which windows mode you are using.
