illuminate vendors not found in PhpStorm since Laravel 8.36 upgrade

Since I’ve updated to Laravel 8.36 PhpStorm can’t autocomplete and doesn’t find the vendors… what’s the problem ?

Answer

If you have recently upgraded your IDE to 2021.1 version then please do the following:

1. File | Invalidate Caches...
2. Select top 2 options (maybe only 1st will be enough, but better use both)
3. Use Invalidate and Restart button there
4. After the IDE will restart, open the project and let re-indexing to complete.

P.S. On Mac the screen visually looks a bit better than my Windows 10:
