Auto-completion/suggestions/formatting not working,

Problem description:
The editor auto completion does not work. Even I hit command + S, the saving is continued forever. When I refresh, I see that the save I previously triggered is done but it was not reflected the last time. The language suggestions and auto-formatting are also not working in the editor. This is happening for all languages but I primarily code in Go.

Expected behavior:
Auto Complete + language suggestions + formatting should work in editor.

Actual behavior:
None of the three work.
