LightBurn Bridge LightBurn Camera integration?

Hi and Happy New Year!
I took me a day to install and get the Raspberry Pi4 up and running with the USB 8MP cam.
The installation guide did not work that good. But this guide lead me the right way:
Secure Webcam streaming with MJPG-Streamer on a Raspberry Pi (sigmdel.ca)
So the Raspberry Pi 4 is attached to the Laser and the camera is automatically streaming.

But I have the same issue, in LightBurn with Virtual OBS Camera - it does only show a black screen.
In Firefox or in OBS, the USB cam streams perfectly.

But I can run Skype and see the OBS Virtual Camera stream without issues.

Installing the IPCamDriverInstaller gives me a livestream.
Atm I did not decide if I should buy the full version of it.
I’m running Windows 11 and there you have to disable Core Isolation Memory feature (driver signing) to get the driver up and running. This is something I personally dislike about it…

So is there a solution for OBS Virtual Camera?
