Dear JonathanShapiro,
Hello! Welcome to the Microsoft Community. I'm glad to be able to help you. If I don't understand your question, please let me know immediately.
I understand that you have an error with error code 0xd0000225, which usually indicates that the Windows operating system has encountered a problem at startup.
The usual solution is to let an account enter the system, then rename the NGC folder, or delete the contents of the NGC folder. The NGC folder holds the user's biometric data and other authentication credentials. Deleting this folder will reset the settings related to authentication.
Similar failures that prevent users from entering the system have actually occurred all the time, and this problem has not been solved yet. But I believe this problem will be solved in a later update.
About the account login to the system, the usual means is to find a way to create a local administrator account. You can refer to the following:
You can follow the steps explained in this discussion to create a new local account on your computer, without connecting it to a Microsoft account or using a password. This process doesn't need an internet connection, and it works for Windows 11 as well:

According to the method here, enter the command prompt with administrator rights.
The command to create a local administrator account is : (replace username and password with your own account and password)
net user /add username password
net localgroup administrators username /add
After creation, you can log in with this newly created local administrator account. After entering the system, you may need to continue to perform the following operations:
Search for CMD, open a command prompt as an administrator, and enter the following command:
takeown /f %windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC /r /d y
icacls %windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC /grant administrators:F /t
Then in the file explorer-> this PC->C drive-> windows-> service profiles-> local service-> appdata-> local-> Microsoft-> NGC path, back up the files in the folder to another location, and then delete all the contents in the folder, but don't delete the NGC folder.
Restart and see if you can log in to the account. If you can, please set the PIN code again. Then remember to put utilman.exe back where it belongs after.
I hope the above information can be helpful to you. If you try the solution, feel free to tell me the results or the problems you encounter.
Best wishes
