Zigbee2mqtt lost connection to all devices after restoring HA backup

Hi,

I had to restore a backup as my computer virtualbox crashed somehow. I luckily had a backup from a few hours ago, so I thought the impact was going to be minimal. Unfortunately Zigbee2mqtt lost connection to all my devices, none are shown in the frontend.

I did restart z2m and home assistant without any effect.

Strangely I do find a file called “Devices” with all my devices listed, see screenshot.

Is there any way to restore this, so I don’t have to add all devices manually again?
