A repository containing full reproduction example will help. Also are you running with these flags:

...
    "go.languageServerFlags": [
        "-trace",
        "-enhance-signature-help",
        "-format-style=goimports",
        "-diagnostics-style=onsave",
        "-maxparallelism=8",
    ],
...

I.e., -format-style=goimports.

somehow if I manually add the import and restart the editor, it all start working again.

If it happens again I'll come back and re-open with more details report
