After Effects Installation fails on Mac OS 12.2.1 error code 183

first, use the "alternative download links" at page bottom here and install the cc desktop app for apple m1 computers, https://helpx.adobe.com/download-install/kb/creative-cloud-desktop-app-download.html

then install after effects and/or premiere pro

if that fails, you probably need to install rosetta 2.

among the ways to do this is to start Photoshop with the Intel version*.

here are two other ways - How to Install Rosetta 2 on Apple Silicon Macs (osxdaily.com).

that's been the solution to a recent surge in mac problems (with new apple silicon macs) caused by premiere pro (and after effects) installs resulting in exit code 183.

there are also the older problems and fixes https://helpx.adobe.com/download-install/kb/fix-error-183.html,

but you should try the rosetta 2 install first, because its absence is most likely the cause of your problem.

*Go to Applications > Photoshop > Open the Photoshop Folder > Click the Photoshop Application within the Photoshop folder.

Then hold Control > Get Info > Check the box for Open with Rosetta
