External camera connected to iPadOS over type-c usb sometimes sporadically stops working

We connect our camera using type-c to an iPad then start a Zoom call. Meetings starts ok - video stream from external camera is working. Then we are trying mute-unmute several times and camera becomes black. Also there is a big lag when external camera is being muted - whole application freezes for ~10 seconds.

This doesn't reproduce with internal cameras. And we tried many other usb cameras as well as different iPads - same issue.

STR:

1) Connect type-c camera to iPad.

2) Make sure video stream works and external camera is used.

3) Press mute/unmute many times.

Actual result: at some point camera stops working.

Expected result: camera works.

Device: iPad mini (6th generation)

OS: iPadOS 18.7.1
