Default Limp Mode?

P2121, C1203, C1A40, C1A50, B2322, U0199
Car is in “reduced engine power” out of no where, its very random but consistent since it started a couple of days ago. I noticed an issue with not having cruise control about a week ago but otherwise no issues.
2017 Lexus RC200T 126k miles
Mods that may have something to do with the issue:
Catless downpipe
cold air intake
Pedal commander
Car is un tuned
