Help! Dashboard lit up after cat replacement

I have a Gen 3 (2014) that got the cat stolen in NYC. The mechanic shop quoted $1500 for aftermarket install. The car had no problems when we dropped it off, just missing cat and O2 sensor.

When we went to pick it up the mechanic said the car has computer problems also and we saw the dash was lit up. He say his upscale computer isn’t resetting it.

I attached a pic but It’s ABS light, brake light, traction control, and some others. The codes are C1203, C1232, C1336, C1345.

After driving a couple days as he suggested the codes didn’t go away so he opened the steering wheel and say we may need to replace the clock spring and Steering Angle sensor.

I asked him if maybe the tech working on the Catalytic converter messed something up but he says he checked everything. This shop did a bunch of work on another car of mine recently and there wasn’t an issue after ward so I’m confused.

Anyone have a clue what might cause this? I saw there’s a bobby pin method to reset the lights but I haven’t tried it yet.
Any input appreciated!!!
