On Android 14, I can start the first camera, but the first camera preview was blocked when the second camera preview started.
I have checked the function void UVCPreview: do_preview(uvc_stream_ctrl_t *ctrl) on 'UVCPreview.cpp' and I think that do_preview function can not run on multi thread.
Please check it.

P/S: Android version less than 14 still works normally.
