Memory error when using rank formula

[Anonymous]

I have a measure "App version sorted Total Duitable Shpmts Col", and for each unique [ecom source name] which is a column, there is a number in the measure. 

I want to display the [ecom source name] with the highest number in the measure "App version sorted Total Duitable Shpmts Col".
I have created the following measure to obtain the [ecom source name] with the highest number in the measure "App version sorted Total Duitable Shpmts Col":

Most used App Version =             
MAXX(
TOPN(1, 'CIN Data Quality', [App Version Sorted Total Duitable Shpmts Col], DESC),
[Ecom Source Name]
)

The formula works fine for small numbers of rows when I filter the table visualisation.

But when I don't filter, the table has over 200,000 rows, which leads to an error as shown below in the card:

When i click "see details", it shows the error below:

Is there a way I can obtain the [ecom source name] in the visualisation without ranking them?

1. Create a measure to find Maximum of measure.

Most used App Version Total Duitable Shpmts = MAXX(ALLSELECTED('CIN Data Quality'),[App Version Sorted Total Duitable Shpmts Col])

2. Create another measure to find [ecom source name] value when measure = maximum value above.

Most used App Version = 
CALCULATE(MAX([Ecom Source Name]), FILTER(allselected('CIN Data Quality'),[App Version Sorted Total Duitable Shpmts Col]=[Most used App Version Total Duitable Shpmts]))
