PDF Icon is blank in Mac Mail and Outlook for Mac

Ventura 13.2 update does not fix this on an M2 Mac. I've done everything from a brand new MacBook (out of the box) build to uninstalling Acrobat, reinstalling, removing plist, rebuild. Reinstalling Office 365, clearing cache, problem still exists. The PDF icon does not show up in Outlook or Apple Mail. All my employees, 30+, are complaining. We send a lot of PDF's with finance and accounts and seeing blank icons can look unprofessional and some think it's a phishing attempt by other 'fake' employees. It is also hard to distinguish between files in attachments and is causing delays for everyone, as they have to double check that the file is not corrupted or they are actually sending a PDF. 

This is a MAJOR issue and it's been 3 months now with no input from Adobe or Microsoft yet. 

Attachment shows the issue. PDF icons used to show before Ventura. All other icons appear.
