Okay, I have been able to isolate this to the vscode 1.62.1 release. The error does not occur in the 1.62.0 release. When updating to 1.62.1 with no other changes, the ngcc process fails.

We are still actively investigating this issue and are tracking https://github.com/microsoft/vscode/issues/136988 as the likely resolution.

In the meantime, the error we show does give the appropriate information. ngcc failed to run, which might cause the language service to not work correctly but can be resolved by npm/yarn run ngcc. Or if you are already running a dev server, ngcc likely already ran and you don’t have to do anything.
