I bet it's all the same issue as I'm seeing with an ASI183MM and a NanoPi M4.
The problem is Linux kernel related, I see errors reported in dmesg when the camera fails to download the image.

I can find later kernel versions that fix the problem with USB3 cameras, but (so far) break the WiFi at the same time.
