macos – Time machine restoration frozen at “Preparing to restore “Macintosh HD”…*

I am using Time Machine to restore a new MacBook Pro 16″. I am using an encrypted HDD that’s connected with USB 3 for the restoration.

However, since about an hour the Mac is frozen at the step “Preparing to restore “Macintosh HD”….

Is this behavior normal? How long should a restoration take? Or should I restart the Mac?
