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

Commencez par reproduire la configuration de référence de projet Angular signalée dans VS Code, en vous concentrant sur les suggestions d’importation automatique avant que le symbole référencé n’ait été importé ailleurs. L’issue ne mentionne aucun fichier du dépôt ni aucun test ; le travail est considéré comme terminé lorsque les imports provenant du projet référencé, y compris src/environments/environment, sont suggérés de manière cohérente dans les fichiers nouvellement créés.
