FS 2020 can't select aircraft or airport and Fly button is missing on the world map after the 1st flight

Same problem if no airports or addon planes in CF.
Removed EVERYTHING from CF and pc hard crashed twice on loading MSFS.
Suspect an external addon like FSUIPC//simbridge/better bravo lights is expecting something in CF.
Put my essentials back as they have been stable commercial addons for 6 months.
It’s something to do with my msfs build I am sure, I have most content installed but have removed some default hand made airports that conflicted with major addons.
It suddenly started this bug a month ago. After that outtage everyone had in 2020 a few days after 2024 was released. There was a small 87mb update i think and then it started.
