Can't connect I-Phone with OBS camera app

[ReilandMusic]

I'm trying to use my Iphone as a camera in OBS with the camera app on my phone, connected via usb. It worked previously, but with no changes in settings OBS software suddenly will not recognize the phone. On the phone app, it says "USB: Waiting for connection," and on the OBS screen is blank when I select the IOS camera. Any help is appreciated!!
