Steps to reproduce

Unknown steps (sporadic misbehavior)

What is expected?

Basic features should work:

• IntelliSense/autocomplete
• Linting/type-checking
• Cmd+Click to jump to definition

What is actually happening?

Randomly, these features stop working. To fix it, one needs to reload VS Code.

Possibly due to tsserver crash, please check the logs and assign more memory.

If still happening please provide a minimal reproduction.
