Can you tell me whats is wrong...

This sounds like either BlueZ or DBUS is not installed (or somehow not installed correctly?). What Linux distro are you using?

[mwende]

i Use Ubuntu 22.04.1 LTS on an Proxmox VM... DBUS is installed and running.
I try your Script on diffrent Clients WSL, Proxmox and diffrent distibutions

[warhammerkid]

It appears that by default Proxmox will not pass access to the Bluetooth hardware to VMs. Have you configured it to pass client access to whatever Bluetooth device you are using? If you run hcitool dev inside your Ubuntu VM, does it list a device?

$ hcitool dev
Devices:
        hci0    00:11:22:33:44:55

It appears that WSL has no support for Bluetooth at this point in time, so that won't work. However, if your host machine is Windows you should be able to install Python and run it there if you'd rather not deal with the complication of a VM.
