Registry query not working with subprocess command

Question

When I enter this in my CMD, it works fine:

reg query "HKLM\Software\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform" /v BackupProductKeyDefault

However when I run the exact same command with subprocess in python, such as:

import subprocess

command = f'reg query "HKLM\Software\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform" /v BackupProductKeyDefault'

print(subprocess.check_output(commmand))

It gives me this error (I made it shorter to make it more readable):

ERROR: The system was unable to find the specified registry key or value. Traceback (most recent call last):
