Dear Shane Thurber,
In many cases, this may be due to a delay in synchronization between your organization's identity system and your local device. We recommend ensuring your PC is connected to the internet and allowing a few minutes for the password change to propagate. If the issue persists, try logging in with your previous password or using the “Forgot Password” option on the Windows login screen, if available.
Additionally, if your device is joined to Azure AD or a local domain, your IT administrator may need to manually sync credentials or verify group policy settings.
I hope this helps. Just kindly tick Accept Answer that others in the community facing similar issues can easily find the solution. Your contribution is highly appreciated.
Best regards,
