I can confirm after 3.4b3 improper homing of the c motor.
Additional info I haven't seen mentioned.
After a system reboot, it will work correctly on the first instance of running home all but subsequent homec or home all will move the c motor in the wrong direction.
for example in homec.g, the first instance calls for G1 H2 C-500 F5000 but appears to actually run G1 H2 C500 F5000 when observing the behavior.
to recreate, reboot ->homeall then either homec or home all will put the coupler in the wrong position.
It does appear that homeing the other axes are involved in this as after the first reboot homec works every time.

did you add the enable mesh leveling to you start gcode?
G29 S1 ;enable mesh compensation
