Hi @skander,
I took a look. There definitely seems to be a lot of activity going on in the client. Did you happen to perform a lot of reorganization recently?
There are lots of items in the trash, which is likely contributing to the menu rendering.
It may be best to use the CLI to see a full list of what is in the trash: Errors when trying to sync deletes
You can then use the CLI to empty the trash, if everything looks as expected in the list. At the bottom of the post linked above is a one-liner script that can be used to ensure that the trash gets emptied, even if it encounters a few errors along the way.
If we can get the trash cleared out we can then see if anything else needs to be looked-at.
