    Try

    MinVoltageN =
IF (
    ISINSCOPE ( TRACKSHEET[REGION] ),
    VAR _minV =
        MIN ( datatable[VOLTAGE] )
    VAR _showminvoltage =
        SWITCH (
            TRUE (),
            VALUES ( TRACKSHEET[REGION] ) = "EU"
                && _minV < 9
                && _minV > 5, 1,
            VALUES ( TRACKSHEET[REGION] ) = "US"
                && _minV < 12
                && _minV > 5, 1,
            BLANK ()
        ) -- Notification
    VAR _Notificationminvol =
        IF ( _showminvoltage, 1, 0 )
    RETURN
        _Notificationminvol
)

My guess is that the problem was triggered in the total line of a table or matrix value. If the region wasn't filtered down to a single value, as would be the case for a total, then VALUES will return all the regions as a table, and you can't compare a table with multiple rows with a scalar value. By checking ISINSCOPE you are guaranteeing that there will be only 1 value returned and so you can compare that to a scalar value.
