All my Nexa and Namron things stop to work

When I try to reinstal the nexa/Namron app because it stop to work (Homey Bridge), this came up " A Driver with ID homey:app:se.nexa:CMR-101 already exists.

All my Nexa and namron things are dead, and i`m not allowed to instal these two apps anymore, because “they are already there” Pleas can anyone help med with this, or tell me how I start over again?
