Apple has posted a support document detailing how to fix an error you could encounter when reinstalling macOS on an M1 Mac.
If you erased your Mac with Apple M1 chip before updating to macOS Big Sur 11.0.1, you might be unable to reinstall macOS from macOS Recovery. A message might say “An error occurred while preparing the update. Failed to personalize the software update. Please try again.” Use either of these solutions to reinstall macOS. You should then be able to use macOS Recovery as expected when reinstalling macOS in the future.
