cmd + m not retaining the shortuct

hi there! hopefully I'm just somehow missing something and need an assist.

I am on a Mac Studio OS Sonoma 14.1.2

I use shortcuts a lot, one of them being the cmd + m to send comp to render. However, it instead minimizes the screen. Which I understand is a system setting and not an app setting.  However, if I go to Edit --> keyboard shortcuts --> and then actually change nothing, merely open the keyboard shortcuts menu options, then that shortcut works again. However, it does not retain it once I've closed out of After Effects and returned later. 

I consider myself to be relatively savvy on these things and I'm stumped and super frustrated.

Thanks!
