System.ArgumentException when using the 'messages grouping' tab with a log file that contains custom columns

[Numpsy]

Describe the bug

I was using the 4.2.3.0 viewer release to view a test Serilog/Clef file and look at the custom columns added by the custom columns feature, and when I tried to use the Messages Grouping tab/feature, I got a message box popup containing

To Reproduce

Open that file with the Serilog parser

Switch the view to the 'messages grouping' tab

enter a number in the 'group by text length' box and click 'set length'

Result: A message box about an exception pops up.
