Equation editor renders properly on screen but does not print properly

For multiple people at my workplace, on both their home and work computers, Equation Editor expressions are often not printing properly, either to pdf or to physical printers.  On screen, everything shows correctly.

It's especially frustrating because equations are partially rendered -- cos x  will be printed as co , a polynomial expression will be missing the last term, etc. -- which means that the errors don't jump out in a quick look at the printout or pdf.

As far as we can tell, the longer you wait after opening the document in Word, the more renders properly, but there are no guarantees, and there are often a great many errors on a one- or two-page sheet with lots of formulas.

I didn't see this problem before this last year or so.  We are using version:

Word for Microsoft 365 MSO (Version 2604 Build 16.0.19929.20164) 64-bit
