I have this problem when connecting the Phantom 4 pro drone with the pix4D program, what would be the solution?
I would suggest to check the recommendations of this article for an optimal experience:

Especially make sure to have the latest Pix4Dcapture, Ctrl+DJI, and drone firmware version installed, and that DJI GO 4 is not running in the background.
