problem

i'm not sure if this comes from the plugin or neovim, but still crashes should not happen.
i use my tree, with the option to keep the tree open when changing/opening a new tabpage.
few issue arise:
when doing tabnew and closing the tree, i then have no way to close neovim bd, qa, q, tabclose actions do not work.
If i'm doing a cheakhealth after opening neovim, the file explorer stays open in the new tab, do a few :bd and neovim crashes with either double free or an invalid pointer being freed.

I'm not too sure but this might be caused by the scheduled callbacks for syncing the tree.

expected

no crash
