Temporary Contacts Unable to be Processed

[CSmithGiGis]

I have event attendees in temporary contacts that produce the error “Attempt to de-reference a null object” when clicked on. I currently have all C&P Permission Sets enabled on my profile.
Could I get help in getting this resolved?
I have granted one-week access using org id: 00D50000000N4jI
