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

Empieza reproduciendo la configuración de referencia de proyecto de Angular indicada en VS Code, centrándote en las sugerencias de autoimportación antes de que el símbolo referenciado se haya importado en otro lugar. El issue no menciona archivos del repositorio ni pruebas; se considera terminado cuando las importaciones del proyecto referenciado, incluida src/environments/environment, se sugieren de forma coherente en archivos recién creados.
