Crash when starting (Chrome too)

Old(er) Mid 2010 MBP with Catalina patched in. Just put new external monitor on. Used to get an opening crash but would be stable on relaunch. Now every opening of Brave or Chrome gets the same abend. I’ve had the graphics surgery done by Rossman. There are similar threads, now locked. But their solutions did not seem to help. I am writing this with Safari.
Here is the Chrome dump:
