Yaml syntax errors in .clangd file leads to unhandled exception

[ghentschke]

If the .clangd file has syntax errors like:

CompileFlags: {CompilationDatabase: Release

and the active build configuration of a MBS project will be changed, an unhandled exception is thrown. The org.eclipse.cdt.lsp.clangd.ClangdConfigurationFileManager should not update the .clangd configuration file in the projects root, because the file syntax is corrupted. It has to be fixed first.

The unhandled exception:

!ENTRY org.eclipse.ui 4 0 2024-02-06 07:28:33.679
!MESSAGE Unhandled event loop exception
!STACK 0

                  ^
