I have inlayHints turned on for TypeScript, as well as bracket pair and guide colorization.

I was searching through a number of files, clicking on each one pretty quickly, and then at some point I started getting an error Unable to open file : Model is disposed!.

clone the TypeScript repository
set the following settings:

    "editor.bracketPairColorization.enabled": true,
    "editor.guides.bracketPairs": true,
    "editor.inlayHints.enabled": true,
    "typescript.inlayHints.variableTypes.enabled": true,
    "typescript.inlayHints.enumMemberValues.enabled": true,
    "typescript.inlayHints.parameterTypes.enabled": true,
    "typescript.inlayHints.functionLikeReturnTypes.enabled": true,

In the Search View, look for const enum (this is the exact query i was using)
Now pretty rapidly start clicking on files in the search results pane
Eventually (after clicking on like 15 to 20 files), especially after opening something large like tsc.js, you'll get the Model is disposed error.

When I checked the console for errors, I found this stack trace that referenced bracketMatching.ts a few times, so I'm not sure if its related or coincidence.

also saw this call stack
