AE 2021 not closing
had been working on After Effects 2021, but for some reason I am unable to open or close it. It says here that the app is open, but nothing pops up. The issue continues to extend to now, it's been around 12 hours since it started.

Whenever I try to force quit it, it just...doesn't happen? I tried force quitting from the dock, from the Force Quit Applications function itself, but it's just...unresponsive. I also tried locating it on Activity Monitor, but I see nothing...

I am currently using AE 2022, which seems to work just fine for me, but I just want to close AE 2021. What should I do?
