I think about #1813, #1833.
Perhaps typescript 3.9 does not listen about extra file extensions change?

This will require some investigation - it should be work based on everything I understand.
I won't have bandwidth to look into this for some time, however.

FWIW, I often get this error (usually on existing Vue single file components I've had open in the editor for a while) and then quitting and reopening VSCode makes it go away. It usually pops up again after a few hours, and I have no idea what's happening to trigger it though.

You can downgrade TypeScript to 3.8 temporarily.

The problem is still present with TypeScript 4.0.2 (2020-08-21) and 3.9.7 (2020-07-16). On the other hand, the older 3.8.3 (2020-02-28) works fine for me.

@sheetalkamat You made a fix in TS related to 1813. Do you expect the change to fix this issue? If yes, in which TS release version will it be included?

Vue is just not well supported by this project.

I don't have any experience in Vue, and I don't have the cycles to learn Vue and investigate whilst also maintaining everything else.

We'd love for someone from the Vue community to champion support.

Without a champion, this will likely remain broken.
