OBS no longer works with my Canon

[TamaraTavellaArt]

I've been using OBS with my Canon 750d for a while now. It has always worked perfectly. But now suddenly the camera stays in data transfer mode and no longer connects to OBS. What could that be? What can i do?
I deleted Obs and reinstalled it, as well as Canon Webcam utilities. I am using a MacBook Pro.

try to change the settings in the camera. like the ftp or resolution until you see that it match with OBS
