ERROR "Cannot find file" _projects, when I delete all projects from folder

[AndreaMoschetto]

If I delete all projects from _projects folder the link checker says:
[ERR] file:///home/runner/work/AndreaMoschetto.github.io/AndreaMoschetto.github.io/_projects | Failed: Cannot find file

I think it's because if you delete all files inside a folder, that empty folder disappears from GitHub and than the link checker doesn't
see it. How can I leave the "_projects" folder empty without raising errors?

Probably the error is due to the projects collection defined in _config.yml. Remove the lines that reference it and it should be fine.
