Steps to Reproduce:

I have an Angular project, and just 1 of the files don't have a proper suggestion support in it.
Same happens when I create a file via plus sign from the side bar.
VSCode doesn't suggest "obvious(necessary)" things, quite the contrary happens:
it suggests everything else what's available, but not what I need and not what really exists in the project.

Also, when I try to import environment object with 'src/environments/environment',
it doesn't seem to know about src folder(project_name/src).
Although it already works this way for all the other files in the project.

Cache cleaning && insiders build didn't help out, no errors in debug console and I couldn't find any useful tsserver logs.
Although I can send if necessary.
Having 3.9.7 TS

Does this issue occur when all extensions are disabled?: Yes

Inizia riproducendo la configurazione di riferimento del progetto Angular segnalata in VS Code, concentrandoti sui suggerimenti di importazione automatica prima che il simbolo referenziato sia stato importato altrove. L’issue non indica file del repository né test; il lavoro è completato quando gli import dal progetto referenziato, incluso src/environments/environment, vengono suggeriti in modo coerente nei file appena creati.
