Installation failed, reverting ./composer.json and ./composer.lock to their original content.

[RuntimeException]
Could not scan for classes inside "tests/fixtures/backend/models/UserFixture.php" which does not appear to be a file nor a folder

Anyone faced same issue? Pls help

Also tried removing the vendor folder and tried running composer install but same issue comes up.

@w3labz what happens if you remove the lock file as well (composer.lock)?

You can also try removing the autoload-dev section from composer.json and re-run the command, as it appears - I assume - that you have installed Winter through the Installer here. The installer does not include development or testing files.
