I'm having this problem with the new version (7.0.0) for a long time.

VS Code takes over a minute to suggest autocompletions, sometimes even 5 minutes.
Because of this, my development is probably slower than without ProbeJS.

If you are on 1.20.1, use v6.0.1 instead.

I finally managed to do that. 6.0.0 was failing because of Create: Deepfried.
The most random mod possible.
