ID: -54 error when saving a file that is active in After Effects CC2020
Having trouble with an AI file that I've imported into AE, each time I make a change the the AI file and save, I get an ID: -54 permissions error.
It worked once, and all saves since have returned the error:

Closing After Effects and saving again in AI resolves the issue, but this never happened in the past and is quickly becoming a very frustrating workflow.
Windows 10 Pro (1903 build 18362.476)
AI and AE files are in the same local folder.
New install of Illustrator CC 2020 version 24.0 and After Effects 17.0
