Some updates for After Effects CC 2021 18.4.0 and up:
Camera tracking works as usual with my method but Stabilization stopped working because of a missing symbol in the replaced libiomp5.dylib:
Dyld Error Message:
Symbol not found: ___kmpc_critical_with_hint
Referenced from: /Applications/Adobe After Effects 2021/Adobe After Effects 2021.app/Contents/MacOS/../Frameworks/libmkl_intel_thread.1.dylib
So I replaced libmkl_intel_thread.1.dylib with libmkl_intel_thread.dylib (obviously renamed) taken from Adobe Media Encoder 15.2 and Stabilization started working again. I'll attach the file here, just overwrite it in Frameworks folder inside AE app just like libiomp5.dylib.
Premiere still need fixes, working on it!
