cannot mount root

When I try to mount the root of a jailbroken iphone:
`
ifuse /mnt/iphone --root
`
the commands hangs for about a minute, than returns:

`There was an error accessing the mount point: Input/output error`

Linux 6.15.3-arch1-1. Ifuse 1.1.4 (was installed from Arch repo, but should be in the latest version). Iphone 13 mini jailbroken by Dopamine.
