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.

Any additional comments?

Same Issue here.

[RayGuo-ergou]

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

If still happening please provide a minimal reproduction.

Also, the Add Line Comment and Remove Line Comment randomly stops responding, and then randomly starts working again.

I just enabled TS Server logs. If I find anything of note, I will report back.
