Help! AE Beta v24 suddenly stopped working on Big Sur

[ellisb85178940]

My AE Beta project stopped working for some reason.

Apparently v24 isn't compatible w my Operating System, Big Sur.
Big Sur and AE Beta v24 are what I used to create the project initially, so this doesn't make any sense. 
What happened and how can I fix it?!

I keep getting this message when I try to open:

Oh, I am sorry you have gotten caught up in this transition period. MacOS 11/Big Sur will not be supported with the final 24.0 release and a change was made earlier in the week in AE beta builds (from 24.0x37 on) so that AE no longer runs on Big Sur in preparation for that. More information can be found here on that change: https://community.adobe.com/t5/after-effects-beta-discussions/updated-system-requirements-for-after-...

You will need to upgrade your OS or open your project on a different machine that has the supported OS and Save As a 23.* project to open it on your Big Sur machine with AE 23.6. Again, sorry about this!
