On startup - internal verification failure, sorry! resource fork usage has been deprecated
I get this pop up everytime After Effects starts up.
I'm on a 2019 iMac running macOS 11.2.3 with the latest version of AE 18.0.0
It seems plugin or script related, because it showed up when I copied all my Plug-ins/Presets/Scripts folders over from my After Effects 2020 folder to the new 2021 folder.
