After several tests, I found that I had the following problems.
1. The ParkOff button on the mount controller is not functioning.
2. The default value of the mount is no longer North Pole.
If I click ParkOff multiple times in the control panel of the mount driver and Sync the incorrect mount position with the North Pole, I can use it, but even after saving the driver settings, if I reconnect the driver, I cannot use it without repeating the above steps.
