The Settings app will crash after changing your account's password or PIN, if you want to change your password or PIN, use the Ctrl+Alt+Del method to change the password.
Due to a merge conflict, the settings for enabling/disabling Dynamic Lock are missing from the sign-in settings.
Settings will crash when the option “View storage usage on other drives” is clicked, which is located under System -> Storage.
The Windows Security app may show an unknown status for the Virus & threat protection area, and sometimes it may not refresh properly.
The option to delete the previous version of Windows in the configuration for Storage Sense is not selectable.

Some apps and games may cause the system to crash with a green screen with the error code SYSTEM_SERVICE_EXCEPTION in win32kbase.sys.
An update block was put in place for this build for a small number of PCs that used Nuvoton (NTC) TPM chips with a specific firmware version (1.3.0.1). It was due to a bug causing issues with Windows Hello face/biometric/pin login, causing it to not work.
