PDF Error Message

We are using SharePoint 2019 on-prem, and are having an issue with a few PDF documents that are being loaded to a document library.  Attached is a screenshot for reference, but when a user tries to open the PDF, they get a "Failed to load PDF" error message.  I've tried resaving the PDF, renaming the PDF, and uploading the PDF to a different library, but still get the error message.  Not all PDF documents behave that way; I uploaded one last week without any issue.  And the file size isn't an issue.  I've checked the PDF to see if there are any security issues, but the PDF doesn't show any.  

Has anyone had this issue and know how to resolve it?  

Thanks!
