Stand up
Look here:
When restarting the camera should be recognized again - is there no corresponding message?
No, not.
Have you tried reverting Windows to a previous restore point?
To be honest, I have no idea how to do it
Control Panel \ All Control Panel Items \ Restore, select "Open System Restore", "Select a different restore point" and select a restore point that was prior to the first occurrence of the problem. Confirm the subsequent query and follow the instructions.
