Have to "Force Quit" on Mac when trying to save as PDF/A

[douglas5E1D]

I have been trying, for the past hour, to save a document in Adobe Acrobat DC version 2021.001.20135 as a PDF/A

This is the first time this has happened when attempting to save as a PDF/A -- normally, it saves just fine

I have tried this on both my Mac Pro (Intel) and my Macbook Air (M1)

The document is 1500 pages long and will save as a normal PDF but freezes and then I have to Force Quit every time I try to save it as a PDF/A

Any help would be very much appreciated

Thank you
