Error mid-print.
Previously got this error
The only thing I can think of is that the stepper motor of the extruder previously got a bad ball bearing and was dissembled to install a replacement bearing.
It already gives you a hint: short circuit on phase B and an open circuit on phase A of the extruder motor/stepper driver.
So you should check the extruder motor, cable and connectors on both ends and the stepper driver itself.
Does the error persist after a restart of the printer?
If so, can you disconnect the extruder motor and verify whether the error is gone or not?
Can you connect a different motor just for testing purpose and check whether the error is gone or not?
