ABS sensor ring

Yeah, but my car has developed a new problem where it’s uncontrollably revs up until it throws a light on for the abs fault. Once the abs is off car drives fine(minus abs) Wtaf?

Not sure about that one, I guess that the ABS error does not show up until the car has tested that system, which means the car needs to be move/driven a few yards/meters.

Does the engine misbehave for longer if you don't actually move the car for maybe 5 minutes, ie before the ABS system has done it's self test?
