New Outlook opening pdf attachment generates application error

[ks1014]

When using the "new" Outlook (1.2025.312.200 (Production) - Client Version: 20250307002.16)
to open a pdf (preview works fine) with Adobe Acrobat DC (64-bit 25.001.20432), it generates this error, that when OK is clicked, proceeds to open the pdf for subsequent use without further issues.

Attempted fixes: Repaired Adobe Acrobat. Changed this setting - Preferences-> Security (Enhanced)-> unchecked the checkbox "Run in AppContainer". No luck.

The same email with pdf attachment works without issue when using Outlook Classic. All other pdfs stored in folders locally, in the cloud, or on network drives open without issue. Seems purely an issue with the new Outlook and Adobe Acrobat. 

Any other suggested things to try, or any news on a fix coming in an update to either Acrobat or Outlook?
