Earlier it worked but suddenly it gave this error.

How long ago was “earlier”?

Looks like you have a problem with your CAN bus.

klippy.log line 892: mcu ‘mcu’: Starting CAN connect
klippy.log line 893: Created a socket
klippy.log line 894: mcu ‘mcu’: Unable to open CAN port: [Errno 19] No such device

Did you check your CAN cabling? CAN termination still correct? What about LEDs on your SKR3 and EBBCAN42? Anything different?

Earlier meant a month ago.
