The camera beeped when taking pictures, and then it crashed.

I have a Sony TRV-46E. There is a fault similar to what you described. I can't record after the beep. I thought it was a mechanical failure or a servo circuit problem. It turned out that the reason was simple. This is the fault of the video tape. After outdoor shooting in winter, the video tape condenses and causes adhesion, the servo motor is overloaded and the magnetic head stops working. I don't know if this is your fault. You can change the video to check it. If there is still a problem with replacing the video tape, it may be a mechanical or electrical failure.
