Big Sur won't even reinstall on my new m1 MBP

I received my new m1 chip MBP today and I tried to reinstall the Mac OS because I sync with the wrong iCloud ID, so reinstallation should be the easiest way for me to erase all the files. 

I erased the disk and everything but the installer just keeps saying ”An error occurred preparing the update. Failed to personalize the software update. Please try again”. 

The system won't install, and now my Mac has no OS at all !

I don’t know what to do, I mean it’s a brand new MBP.
