Google Sheets Importrange statement in SWITCH

I'm using the importdata statement inside in Switch condition and it does not return anything nor give an error.

My formula:

=SWITCH(C5,"Desired Value",IMPORTRANGE("url to the google spreadsheet", "MyTab!A:E"),C5,"Another Value","Another Value Output")

So when it's "Desired Value" is prints nothing. If I write a separate IMPORTRANGE without SWITCH it works fine.

EDIT:

Example
