Error 999999 Summary Statistics tool, ArcGIS Pro

[DiegoLlamas]

Hello,

We are using Summary Statistics tool in ArcGIS Pro 2.6.1 with a File geodatabase layer. When we run the tool with 0.5 millions records the tool crashed

But if we select 10 records, Tool works fine.

But I cannot work 10 records at a time because I will not finish ever if I have 1/2 millions records. 

What Can I do? is this a bug? is this an error from my data? the tool cannot work with that much records?

Thanks, 

DLL

You ran statistics on 4 fields.

What happens if you test each field? 

Since the error is the generic 9999...., it could be something wrong with a field or simply you have too many records times the number of fields
