Visual Studio Code - vue.volar extension - JS/TS language service cannot be started successfully

[nico-sth]

When loading/opening a non-Vue project (e.g. NextJS [React]) with the Visual Studio Code vue.volar extension installed (v2.0.10+) I get the following error message:

Downgrading vue.volar to v2.0.6 or disabling the extension altogether fixes this issue. Loading a Vue project (e.g. Nuxt) does not experience this issue.

Same here suing Vue - Official v2.0.10:

Still an issue in v2.0.14

This problem is really effecting DX... no type completion and refactoring of types is really bad. Productivity down 80%.

Could you share the tsserver log?

OK I think I fixed it for now... though I do not know the reason.

I tried older versions of volar e.g. v2.0.6, but the problem still persisted.

Using now vue.volar@2.0.14, I cloned my project into another folder and started fresh. Now everything is working as expected. Type completion and refactoring now work fine.

I manged to pull a few entries out of the logs as requested.. not sure that helps, but does look fishy somehow:
