Summary
Editor squiggle decorations get stuck and no longer update as we fix/introduce errors. This makes in-editor feedback unreliable until the extension host is restarted.
Eliminated third-party extensions as cause; this started happening across all dev machines at same time after an editor update (I think it was the update before last)
Currently, the language server seems to continue to reflect the already corrected error in the Problems tab, but this behavior may be inconsistent. Previously I think the Problems tab was ok and only in-editor decorations failed to render.
Saw many of these type errors today when opening project:
Ensure condition failed: Sentinel [File:Z:\UEVFS\Root\Engine\Source\Runtime\VerseCompiler\Private\uLang\SemanticAnalyzer\SemanticAnalyzer.cpp] [Line: 9222]

What Type of Bug are you experiencing?
Verse
Steps to Reproduce
Write Verse code.
Make syntax error.
Fix the error.
Expected Result
Expect squiggle/underline decorations to update properly.
Observed Result
Editor squiggles remain on lines that were previously invalid even after the error is fixed, and/or fail to appear for new errors.
Running Developer: Restart Extension Host (or Developer: Reload Window) and ‘Compile Verse’ in editor immediately restores correct squiggles until it happens again.
