Godot incorrectly uses 32-bit .NET SDK even when 64-bit is installed

Tested versions

can be reproduced at v4.2.2.stable.mono.official [15073af]

System information

Godot v4.2.2.stable.mono - Windows 10.0.22000 - Vulkan (Mobile) - integrated Intel(R) Iris(R) Xe Graphics (Intel Corporation; 32.0.101.6078) - 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz (8 Threads)

Issue description

Description

When both 32-bit and 64-bit .NET SDKs are installed on Windows, Godot detects the correct 64-bit SDK version (e.g., 8.0.15) but still attempts to use the 32-bit SDK during compilation. When opening any normal C# Godot project, console said:

/root/godot/modules/mono/editor/GodotTools/GodotTools/GodotSharpEditor.cs:471 - .NET Sdk not found. The required version is '8.0.15'.
  /root/godot/modules/mono/editor/GodotTools/GodotTools/GodotSharpEditor.cs:416 - System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Build, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. 系统找不到指定的文件。

(Chinese inside means "System cannot find the specified file.")

Expected Behavior

Godot should prioritize the 64-bit .NET SDK when both architectures are present, especially if the OS is 64-bit.

Actual Behavior

Godot incorrectly selects the 32-bit SDK, leading to build failures.

Environment

• Godot Version: v4.2.2.stable.mono.official [15073af]
• OS: Windows 11 x64
• .NET SDKs or runtimes:
  8.0.15 (x64) at C:\Program Files\dotnet
  8.0.14 (x86) at C:\Program Files (x86)\dotnet (only runtimes)

Godot v4.2.2.stable.mono - Windows 10.0.22000 - Vulkan (Mobile) - integrated Intel(R) Iris(R) Xe Graphics (Intel Corporation; 32.0.101.6078) - 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz (8 Threads)

Additional Context

This issue does not occur if only the 64-bit SDK is installed.
Workaround: Manually uninstall the 32-bit SDK forces Godot to use the 64-bit version.

Steps to reproduce

Reproduce

1. Install both 32-bit and 64-bit .NET SDK (or runtimes):
   8.0.15 (x64) at C:\Program Files\dotnet
   8.0.14 (x86) at C:\Program Files (x86)\dotnet (only runtimes)
2. Open any C# project with Godot (v4.2.2.stable.mono.official [15073afe3]).
3. Observe the error logs in Godot output panel
