Error when saving as PDF/A

[James24112308zm9e]

When I attempt to "Save as Other" and choose PDF/A I get the following error:

Could not copy file C:\Program Files\Adobe\Acrobat DC\Acrobat\plug_ins\Preflight\PitputIntent\CoatedFOGRA39.pdf, C:\Users\[username]\AppData\Roaming\Adobe\Acrobat\Preflight Acrobat Continuous\OutputIntent\CoatedFOGRA39.pdf; The parameter is incorrect.

I've tried uninstalling/reinstalling. I know the issue is not with the specific pdf, as I get the same error when I try it with any file and can successfully save the files as PDF/A on other systems.

Any help is appreciated.
