In generally, the recording should be the same as what attendees’ saw.
It recommends you open the recording in Microsoft Stream and check if the playback is proper.
Meanwhile, confirm with the recorder and meeting organizer if they edited this recording.
In addition, make sure your client is the latest version. I tested in Microsoft Teams Version 1.4.00.7174 (64-bit). It works well.
If the above suggestions have no help, I have some question want to confirm with you:
Could participants in your organization paly the recording properly?
Except the black box, does this recording contain other information, such as audio or image?
Does this problem persist all the time? Or what changes do you do before happened?
