Are There CSV Row/Column Limits for CSV Files added to the EG Panel?

I have a project that I will be exporting to a MOGRT and will be adding a CSV to the EG panel so users can switch it out. I need to set it up intitally with the maximum number of rows and columns from the CSV file, but am experiencing some issues.

I can successfully add any CSV file to the project and to the comp. However, when I add certain CSVs to the EG panel (from the comp > Data properties) After Effects crashes.

For example, CSVs with 10 rows and 15 columns work, although it takes a little while for AE to parse all the data. A CSV with 24 rows and 25 columns crashes. AE freezes while it appears to be parsing but then the Windows waiting spinning blue circle appears. I've left it for a good ten minutes but it never recovers.

So, is there a limit to the amount of rows and columns AE can parse in a CSV when you add it to the EG panel?
