Unexpected Parameters

[Ricie]

Hello,

I have this error almost anytime midflight, msfs2024.



How can i fix it?

[Captain Kevin]

What are your system specs.

[Ricie]

AMD Ryzen 7 7700X, 32GB DDR5, RTX 4070 Super. Had never problems to run GSX. It's since msfs 2024. Have used it so many times in 2020. But this error is always in 2024 midflight. At the start of the flight everything works well.

Getting the same in MSFS 2024.

It's strange, your log doesn't show any errors.

[JetNoise]

Okay, lets try again with this one ...

Can you point me to the GSX custom profile you are using ?

[fabianlujan]

I'm having the same popup error.
It's boring because it puts itself in focus and move the game to background, forcing to close it.
Seems it happens when approaching an airport which may not be covered or prepared for GSX.[/img]

Have the same issue. It went away after I removed the x64 version MS Visual C++2015-2022 Redistributable.

It came back today with an update to my AMD adrenaline software.

Is it possible to force GSX Pro the refer to the x64 redistributable ? (Presuming that is the culprit)

Application: couatl64_MSFS2024.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an internal error in the .NET Runtime at IP 00007FF9D085657C (00007FF9D0850000) with exit code 80131506.

I downloaded the latest versions of both the x86 and x64 versions but it did not help.

https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-supported-redistributable-version.

Is it possible to disable the concurrent garbage collector for couatl64_MSFS2024.exe ?

Is it possible to disable the concurrent garbage collector for couatl64_MSFS2024.exe ?

THere's no garbage collector at all in  couatl64_MSFS2024.exe , it's not a .NET app, it's a native x64 unmanaged app, so it handles memory on its own, without any connection to the .NET garbage collector.

[fabianlujan]

same here; downloaded both, tried the game and seemed to be everything fine.
today new game, the error returned.

Try running the FSDT updater now, we released a small hotfix to the couatl64_boot.exe that *might* improve this.
