CRASH--Loading space-delimited data

I’m new to ParaView and what I tried to do caused the system to crash. I’m trying to load a data file (.txt) of space delimited numeric values. The displayed default field delimiter character is a single comma. I added a space after the comma and hit Apply. My thinking is that it would look for either a comma or a space delimiter, similar to the Excel data import. The system crashed. I’m using 5.7.0-RC2, Qt Version 5.12.3.
