Adobe Media Ecoder Beta not responding at shut down

AME Beta v22.3 (build 😎 not responding when it is quit. MacOS Catalina 10.15.7. This version of AME Beta performs as expected during encoding of After Effects Beta v 22.3.0 (Build 37) files but does not shut down when quit, instead showing as not responding in Activity Monitor. This occures with every encoding session.
