D415 reports an error and cannot be used

[gaoxiaohuiandy]

I have two D415, both with shells. I have been using them normally for a while. Today, when I use one of them, it keeps reporting errors and the camera is unusable. I found that its serial number has changed to ffffffffffff, it was not such a serial number before. I switched the cables, the other one can be used normally, but this one still cannot be used. There should be no problem with the cable. Is there any solution?
