I was getting regular CTD whilst flying New York area since latest update, happened when I got close to New York Newark airport. It happened 3 times in a row, in roughly the same location. Sim Freeze, then CTD 0xc0000005c in the logs.
I noticed the latest scenery update to USA Scenery II was a patch. So within FS2020 I deleted the USA Scenery completely, then re-downloaded the lot. About 6GB, 10 minutes.
Worked a treat. I flew over Newark no problems. If I get any CTDs in any other location I may try and delete the scenery fully and re-download it from within the sim.
Might not work for you all. Good luck.
