The Vue Semantic Server server crashed 5 times in the last 3 minutes

Volar extention was working perfectly fine until this error appeared out of the blue today. I tried reinstalling vscode and volar. Then I increased --max-old-space-size for node and maxTsServerMemory. However, the error still remains.

VS code version 1.72.0
Volar version: v1.0.1
Ubuntu 22.04.1 LTS

It seems failed at https://github.com/johnsoncodehk/volar/blob/627a3ab84165cd851b471a8350d77f608612dc43/vue-language-tools/vue-language-core/src/utils/ts.ts#L32, I guess you have some tsconfig files it's empty or invalid jsonc format. I will check how to fault tolerance with it, you can check tsconfig content you have before fixs.

Many thanks for the reply John.

You are right, there seems to be an invalid path under references in tsconfig. It does not crash after fixing that. Strangely enough, it did not cause any issues earlier.

I guess this error is ignore by try catch in old version, I kind of want to keep this crash, otherwise when failed users just loses all intellisense without any hints. I will keep this issue open for more time to thinking.

I got this error because I switched the name of a directory that was a workspace in vs code.
