4.4.1.stable

With
export_templates/4.4.1.stable.mono
TargetFramework: net8.0
LangVersion: 10.0

Is there any way to get more details on release build error messages?

A month ago, export a release build worked. But today, it’s throwing a rather useless:

ERROR: editor/export/editor_export_platform.h:243 - Export .NET Project: Failed to build project.

I’ve locked my .Net 8.0 C# project at C# language version 10.0.

I can build and run in the Godot editor just fine.

Click on the MSBuild tab to the far right from the Output tab.

I’ve stared at this for a day before noticing that.
