Can you do an importrange on data from multiple sheets if the data itself has an arrayformula with a textjoin?

I'm trying to summarize a bunch of sheets into one via a query([(importrange)(importrange)(etc.)}. I've done this multiple times without issue, but now the data I'm pulling is has a columns that is populated with an arrayformula(textjoin....
Is the array formula the cause of the importrange (or query) not working? My query is simply "select * where Col1 is not null".=ArrayFormula(TEXTJOIN("; ",true,if('All days'!$D$1:$D$400 = D2,'All days'!$L$1:$L$400,"")))
