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 ?
