Opening After affects and it shows me a message for one second saying you cant run it because you need Cinema 4D or when I want to open after affects normally it says this |(picture shown in the description) and crashes to continue and then it just crashes. I already tried uninstalling and reinstalling it and it hasn't worked. Please help
The image suggests you're running the intel version of AE on an Apple silicon Mac, and it is just informing you that some features won't be available. You should be able to switch the the native Apple silicon version by right clicking on the AE application, Get Info and then uncheck the box about using Rosetta. See if that helps get you going.
