Didn't know how to crosstable and the format column change

I have a vertical table, like this:

I want to query it like this crosstable function:

I have tried ArrayFormula like this:

=ArrayFormula(SPLIT(QUERY(UNIQUE(FLATTEN(IF(LEN(A2:A10&""&B2:B10&""&C1:F1&""&C2:F10)=LEN(A2:A10&""&B2:B10&""&C1:F1&""),"",A2:A10&""&B2:B10&""&C1:F1&""&C2:F10))),"Select * Where Col1 Is Not Null"),"",1,1))

But the column code change into a date. Can I have this code in format text?
