OPen Captivate 4 project in Captivate 5 fails and shuts down Captivate 5

I have a small project (6 slides) that was created using Captivate 4. When I attempt to open this in Captivate 5, I see the progress bar indicating that the slides are being upgraded to 5 and once that completes, I get an error message that it encountered an error and needs to close. I tried a couple other projects created in Captivate 4 and those open fine in 5.

I saved the text file created as a result of the error, but don't know what it is trying to tell me. I don't see an option here to attach the file.

I appreciate any assistance or direction you can provide.
