If this does not help
Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

    Thank you, I took some of your logic and made it into this:

    I created an index column because the customer ID is repetative monthly:

    Index = RANKX (FILTER ( 'Table 1', EARLIER('Table 1'[Customer_ID]) = 'Table 1'[Customer_ID]), 'CTable 1'[YearMonth], , ASC)

     

    Then based the profile off the index numbers.

     

    _Customer Profile =
    varCustomerID = 'Table 1'[Customer_ID]
    var MonthIndex = 'Table 1'[_Month Index]
    var previousCount = CALCULATE(COUNTROWS('Table 1'), FILTER(ALL('Customer_ID'),'Table 1'[Customer_ID] = CustomerID && 'Table 1'[_Month Index]))
    RETURN

    IF( NOT ISBLANK('Table 1'[Customer_End_Date]), "Customer Quit",
    IF( 'table 1'[Index] = 1, "New Customer",
    IF('Table 1'[Index] =2, "Previous Customer", "Same Customer")
                 )
           )
    )
