Had a similar issue with repeated crashes, pretty sure it was that exact error message as well every time, tried inputting that command and went on a dungeon run in the facade zone. Went pretty well for about three floors before I crashed, but the message just said "Fatal error!" and nothin else. So... it's different errors I guess? Notably it crashed right as I was landing an attack in combat so maybe it was just unlucky.
Update, I DID manage to recreate the FATAL ERROR crash the other commenter made.
This was AFTER putting in the command you suggested and saving. I put it in again on a new load and crashed in a dungeon. I reloaded but this time did not put the command in and was able to play uninterrupted for several hours.
