@MichMich Got a similar issue as reported by @schlachtkreuzer6, unfortunately I now have a black screen when starting. Logs show “WARNING! Could not load config file. Starting with default configuration. Error found: Error: Module version mismatch. Expected 50, got 54”. Any suggest on how to revert?

Update: Managed to successfully revert back but doing a " npm install electron".

@paviro Paul-Vincent, congratulation for the Facial Recognition module. I use it on my mirror. Except that I had to position the camera pi at 90 degrees for a cosmetic reason. Would oyu know how / where to configure the camera to rotate 90?
