You are not alone, friend. I also have a freeze after takeoff. It's a pity that I ruined two weekends in pain with airplane problems, but in the end I didn't solve anything.
To be honest, I wrote "flying" but that's not quite true. I made 1 flight.
Now when I gain altitude, my screen freezes)))) I have to hard exit the simulator.
While I'm tweaking the settings on the ground((((
By the way, I load either 900 or 1000 version.
That is, if I fly on 900, then when I load 1000, I get CTD.
I clean out the WASM folder and can load 1000.
And I also have CTD when I add third-party liveries.
I do it like this. I have the Steam version.
I add the folder with the livery to the Community folder.
Then I delete all the files from the WASM folder \MSFS2024\inibuilds-aircraft-a350
My folder arrangement.
C:\Users\Bl\AppData\Roaming\Microsoft Flight Simulator 2024\WASM\MSFS2024\inibuilds-aircraft-a350
