[HumHub] No admin access anymore

My YunoHost server

Hardware: VPS bought online
YunoHost version: 11.0.9.14
I have access to my server : Through SSH
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

No access at humhub admin user

I no longer have access to the admin user that was automatically set up by yunohost. I don’t know if it’s related to the update to version 1.12.1.
How can I create a new user or change the password of the old user in the database?

When I want to change the password of the current admin user, the following message appears:

Password recovery is not possible on your account type!
