P3424WEB, macOS, camera issues

Hello, I have a Dell P3424WEB monitor with an integrated camera connected via USB-C to my Macbook Pro M1 on macOS 14.6 and I keep having issues with the camera. If I disconnect the laptop from the monitor and connect it again, the camera is usually undetected. If I use it on Zoom, the video often freezes and needs to be turned off and on again in the Zoom app.  I have installed the latest firmware for the monitor, Dell Display Manager, but the issue persists. What should I do to fix this? It is very frustrating to have such a cool integrated camera which only works sometimes (typically after restart of my Mac). Also - my colleague reported the same issues on 16" Macbook Pro M2.

Thank you.
