Found a workaround that lets me play without crashing.
Download Nvidia Inspector
Extract the files
Run "Nvidia Profile Inspector"
Find "APB: All Points Bulletin" in the drop-down at the top left
Click on "Delete Current Profile" and press yes when it asks you to confirm
Then you can play APB with your RTX card. You may have to do this every time you update your GFX drivers, not sure.
