Usb camera blue os 1.1.1 dropping

Hello, I had a BR2 running with the 1.0.1 blue OS and the camera worked fine. I did update it to the 1.1.1 version and the camera is not stable. On the web interface I can see the camera plugged/unplugged from the raspberry pi4. So I decided to run the previous version again the 1.0.1 and the camera is working fine now. What can be the issue?
Regards,
