Prusa 3.9 crashes when OP server is restarted

What is the problem?

Whenever I have needed to restart the OP server, since upgrading my Prusa MK3S to a 3.9, my printer has started crashing. The only solution is to cycle the power to the printer, or to press the reset button on the printer.
The most recent crash was after installing the Full screen webcam plugin, which required a restart of the OP server.

What did you already try to solve it?

Reset, or restart printer

Have you tried running in safe mode?

No

Did running in safe mode solve the problem?

Didn't try, but probably not.

Latest OP 1.9.3, connected to MK3.9 via USB c cable. Running on RPI4. Printer error in photo of printer screen. Printer FW5.1 Browser firefox, OS Win11

I just installed the OP plugin to support BGcode from this URL: ```

Not sure if it will help, but I guess we'll see.....

Sounds like a firmware bug
Report it to prusa :slight_smile:

That plugin has nothing to do with this weird firmware issue.
