Has anyone encountered this error or have any idea what might’ve caused it?

It happened a few days after I got my windshield replaced and got it tinted.

The main persistent error code I get is: CDA728

My Toyota dealer couldn’t communicate with my car because they said it was tuned. So they gave it back to me.

I have tried disconnecting the battery for 10 mins, fully charging it, reseating the dash. Everything. I can still flash tunes and use everything in the car.
