MSFS 2020 126.96.36.199 update broke the mods and now the game just crashes
I have exactly the same problem
I just whent through every mod I had to find which ones weren't up to date and removed those. Now it runs fine
I intend to do what I've done before (with success following a string of broken downloads each time) and that is to run a decent VPN into a local server before I start the download.
I don't know what it does, but it sure cured my broken downloads woes.
It's linked to your X-box live account, you need to reset this way :
go to :
delete folders "account" and "cache"
reboot your computer
Find it in msfs forum, it works great
