I did this, still the same problem.
I tried this, and even if the terminal confirmes "disabled", the daemon still comes up after some minutes.
After going to the extreme of completely fresh install 11.2 on a sepratae SSD with the same OC like on the system nVME and exactly the same error occured, I narrowed it down to the mediaanalysisd daemon. I read quite a bit on the net about it, apparently this is more specifcaly looking at videos in the photo library - but correct me if I'm wrong.
On the completely fresh install of 11.2, I logged into iCloud, turned on the Photo sync. It satrted to sync to the cloud and all photos/videos appeared. Then mediaanalysisd kicked in and 2 minutes later it crashed.
I disabled iCloud Photos, deleted the Photos library file all together. Restarted Photos.app, it asks me where the library file is, I say create new. So with the new empty library file mediaanalysisd never comes up at all - and no more crashes!
I did the same in my main nVME system install, so now I don't have iCloud Photos on and the Photos library is empty. And no crash!
I wonder what this strange behaviour is. Don't you all sync your pictures with iCloud? and none of you has this issue? Maybe I have some wicked pictures/videos in my iCloud? Or some video file is causing the daemon to crash...?
So the only workarround for me is to not sync my iCloud Photos - which is not satisfying at all, given that it was working in Catalina. What is Big Sur doing wrong here - if at all. I want my Photos sync back!
Any ideas?
thanks
