Failed to load .NET runtime on Windows 11

[andristarr]

Godot version

4.1.1

System information

Windows 11

Issue description

I am running on Windows 11 and the csharp version of Godot doesn’t load. Always gives me the error in the title.

I have already installed .net sdk 6, .net runtime 6 and the .net desktop runtime 6 for windows.

I have checked and the path to the dotnet distro is in my path (both system and user), running dotnet —version gives me the 6.x… version correctly.

Steps to reproduce

Start Godot on Windows 11 after having .NET SDK 6 installed.

Minimal reproduction project

Irrelevant. Described in issue description.

[RedworkDE]

Please post the output of dotnet --info and the Godot console outputs for further diagnosis.

Additionally ensure that the architecture of dotnet matches Godot.

This now includes my .NET 7 install as well, I have installed it later while trying to debug.

As for Godot output:

ERROR: hostfxr_initialize_for_runtime_config failed with code: -2147450733
   at: (modules/mono/mono_gd/gd_mono.cpp:200)

[raulsntos]

The error -2147450733 is InvalidConfigFile (see https://github.com/dotnet/runtime/blob/main/docs/design/features/host-error-codes.md) and it means:

The .runtimeconfig.json file is invalid. The reasons for this failure can be among these:

• Failure to read from the file
• Invalid JSON
• Invalid value for a property (for example number for property which requires a string)
• Missing required property
• Other inconsistencies (for example rollForward and applyPatches are not allowed to be specified in the same config file)
• Any of the above failures reading the .runtimecofig.dev.json file
• Self-contained .runtimeconfig.json used in hostfxr_initialize_for_runtime_config. Note that missing .runtimconfig.json is not an error (means self-contained app). This error code is also used when there is a problem reading the CLSID map file in comhost.

Make sure you have extracted the GodotSharp directory next to the Godot binary. If this was the issue, 4.2 will provide a better message (see #80212).

This really needs to be documented somewhere clearly AND the error message should be updated saying the folder and it's components are missing. This is a big deal !!!

I was having the same issue and spent HOURS, installing, uninstalling, checking environment variables....

• Closing as fixed by Show alert if .NET assemblies dir does not exist #80212 (which is included in 4.2 or greater).
