Avion et Hélicoptère achetés ne fonctionne plus

Hello, about a month ago I formatted the C on my computer and reinstalled Windows 11 (Windows Professional) because I thought I had caught a verus, I reinstalled MSFS 2020 and the products I bought (the HPG 145 Helicopter from Hype Performance and the Aerosoft Twinn Otter Airplane no longer work, I installed them and when I choose one or the other of these devices I start the game and after a few seconds the game crashes, I tried everything redownloaded the game several times and nothing worked. All the other devices in the game work fine. Please if you can give me some advice it would be very appreciated. Thank you.

I would uninstall both planes, do a reboot of your system, then reinstall and see what happens.

 

Also, you might have some other mods which could be causing the system to crash.
