Odd that the temp would start rising rapidly, causing misfires, and the gear oil went up too?? Yes, if your coolant temp is high, your oil temp might be high too, but gear temp while driving normally shouldn’t be affected. Did the engine sound weird at all, any weird noise or vibrations, could you hear the cooling fans running (they usually keep going after you shut off the engine too)?
Did you write down all the codes? When you say “oil sensor” code - is that the temp sensor? Or oil level sensor? What were the codes saying? High coolant temp doesn’t trigger a code (happens when driving hard on the track, for example). Codes are generated with problems so would be nice to see all the issues.
Could definitely be electrical though - possibly a grounding issue or something. Since it’s a 570, isn’t it under warranty? If so, I’d take it in - the MDS (McLaren Diagnostic System) can see codes that OBD2 can’t, and can also force-run tests all over the engine and transmission, measuring sensor output for expected behavior, etc.
