An unhandled exception of type 'System.MethodAccessException' occurred in ChoETL.NACHA.NETStandard.dll

[chatbot702107]

Upon hitting this line of code, seeing this error below. Any ideas on what is going on with this?

Line of code blowing up is this (trying to use this ChoETL in a .NET 7 console app by the way):
foreach (var data in new ChoNACHAReader(filename))

Exception Type: System.MethodAccessException
TargetSite: Void .ctor(System.String, ChoETL.NACHA.ChoNACHAConfiguration)
