I had the same problem and this file solved it.
In Windows 10 it should be placed in: <installation_path>\Adobe\Adobe InDesign 2021\Plug-Ins

Thank you very much!

We will make sure to include this new plugin version in our next release, so this error should not be occurring anymore.


I am getting this same error in the latest InDesign 16.3 on Windows. I had no error prior to either the Adobe update, or the latest FontBase update. I tried downloading the plugin posted here, but ran a diff and saw that the file was identical to the one I have installed. So replacing the file generates the same error when InDesign is launched (Adobe InDesign does not recognize FONTBASE-INDESIGN-WIN-2021.PLN as a valid plug-in. Please reinstall the FONTBASE-INDESIGN-WIN-2021.PLN plug-in and restart InDesign. Show this alert again?). Thanks for your help!
