Nitropad with qubes freezed when booting

Hello, I have just started with new Nitropad 230. I went exactly step by step as NitroPad with Qubes OS - Nitrokey Documentation
but during finishing step 3 PC got freezed and I cant even move cursor. It shows:

[Dom0] Qubes OS setup
Setting up networking

Edit:
After one hour with this screen I turned off the PC. Now after I turned on there is repeating this message over and over:
gpg: waiting for lock (held by 138)

I dont know what to do, tried to google / find here any solution, but I cant find any

Thanks
