Another Import CSV Error

Hello,

I am seeing the following two error messages in Studio when trying to import a CSV file using the wizard.
1.) An error occurred while trying to read file reported_events.csv (Error TypeError: Cannot read properties of null (reading 'toString'))
2.) An error occurred while trying to read file reported_events.csv (Error NotReadableError: The requested file could not be read, typically due to permission problems that have occurred after a reference to a file was acquired.)

Not sure what is going on? The file I am trying to import has valid CSV data.

Thanks.
Scott
