Camera doesnt recognize lens after waterdamage

Hello everyone.

So about a week ago my 80D got water into the lower body so I put it in a bag with rice for a week. It helped! Anyway now the camera doesnt recognize the lens anymore. Its attaced properly, fully charged the battery, cleaned the contacts, removed the battery, tried different shooting modes & did a factory reset. Nothing helped.

I acticated shooting without lens but then I get the error that there is no lens and I should turn it off (AF & MF are not working)

Is there anyone out there who could help me? Is the lens broken?

I really dont want to spend a fortune in a canon dealership. I really appreciate any help..
