I was on the same boat several weeks ago. There is nothing you can do and you have to try your luck. Go find another job and hoping there will be no RFE. Two ways you will be safe: 1. Nobody will touch you case within 180 days, then you are safe under AC21 2. No RFE Based on my experience and data on Trackitt, USCIS now process 485 around 5- 6 months so option 1 only has small chance to happen.
