Can only use P mode on my one year old R5.

Right now I am traveling and ot seems the mode button is not working. I can not have a choice to us anything but P mode. Autofocus is also a bit unstable. Nothing has happened to the camera vi or lens (100-500 mm). I have tried to reset settings. And also to take out battery etc.

Greetings,

Sorry to hear about your problem.  A reset should include both camera and custom C1~C3 settings reset.  Now remove the lens.  Power on and test changing modes.  If the behavior has not changed, the camera will require service.
