failed to personalize the software update Big Sur

I formatted a MacBook Pro with M1, model A2338, using an USB installer with Big Sur 11.2.2. When the installation shows 34 minutes , the error "Failed to personalize the software update. Please try again. "

Is there any solution for this ?

Thanks

Thanks for your answer HWTech

The only detail I had was that, while the computer was connected to the Mac with the cable, Apple Configurator 2 didm't see the MacBook Pro.

I had to disconnect the cables (Power and USB-C) , and put the MacBook Pro in DFU with the keys, after that Apple Configurator sea the MacBook Pro and fixed the error.

Thank you very much
