My Date Calculation is showing blank all of a sudden

[canddig]

Hello, 

Can anyone help me trouble shoot why my dax formula would suddenly calculate (blank)? It has never done this to me before. 

WorkingDay = VAR UsedDate = Today() -2

VAR FirstDayOfMonth =

DATE( YEAR( UsedDate ), MONTH( UsedDate ), 1 )

VAR WorkDays =

COUNTROWS(

FILTER(

ADDCOLUMNS(

CALENDAR(

FirstDayOfMonth,

UsedDate

),

"WeekDayNumber", WEEKDAY(

[Date],

2

)

),

[WeekDayNumber] < 6

)

)

RETURN

WorkDays

Very simple if you run this code in DAX Studio:

EVALUATE
VAR UsedDate = TODAY() - 2 // today must be 2021-05-03
VAR FirstDayOfMonth =
    DATE( YEAR( UsedDate ), MONTH( UsedDate ), 1 )
VAR WorkDays =
    ADDCOLUMNS(
        CALENDAR(
            FirstDayOfMonth,
            UsedDate
        ),
        "WeekDayNumber",
            WEEKDAY(
                [Date],
                2
            )
    )
    -- [WeekDayNumber] < 6
RETURN
    WorkDays

Thanks! I am still getting an error and I am not sure why? I am seeing it as infinity in calculations or (blank)
