good evening, 

for whatever reasons my adobe after effects 2020 won't start anymore.

it says : ''After Effects can't continue: unexpected failure during application startup''

i got a macbook pro m1 and recently updated to macOS sequoia 15.2

thank u

That version of After Effects is not compatible with that hardware and software combination.  You'll need to run After Effects 24.x or 25.x.
