Error Sharing Files via link with encrypted module activated

I have a big problem.

We need to share files with other people via shared link with password. I’ have activate basic encryption module.
The shared link generation work fine. But if you access the shared link work apparently,
When you press the “download” button the error is : “Can’t read file
Private Key missing for user: please try to log-out and log-in again”

¿ Any solution ?
