Cubase 11.5 Pro Windows 10 MOV file "invalid or not supported"

Receiving a legit MOV file from a legit film production company which I’ve successfully worked with for the past 6+ years. Can’t import the videos in MOV format that they are sending to me. Why? When I go to “Import video file” and single-click on such a video file in the video import dialog box, I see “The file is invalid or not supported” in the lower left corner of the dialog box. But the video file is fine, it opens in other audio and video programs and plays with no problems. Why not in Cubase?

Please help me with this, this is a ridiculous situation!

Thank you!

It won’t be supported then. Cubase has quite a narrow range of supported file types for video. Best bet is to convert them to a supported format.
