Manager Script GUI broken on Linux

[par456]

What happened?

I get the following error when trying to look at a manager script on the linux build:

Exception has been thrown by the target of an invocation. --> The type initializer for 'GtkSource.SourceView' threw an exception. --> GtkSource: libgtksourceview-4-0.dll, libgtksourceview-4.so.0, libgtksourceview-4.0.dylib, gtksourceview-4.dll

And it leaves a blank screen.

What Operating System are you on?

Windows
