Hello @cudell
I'm wondering if we may need to try to validate the file to see if we might be able to find something within the repair. I'll l'll leave steps down below on how to do so.
File > Validate & Repair file > Validate > Ok
Once you get a chance to try these steps, please let us know what you find. From there we'll better understand our next steps/options.
Thanks,
Quicken Francisco
