- This update makes Country and Operator Settings Asset (COSA) profiles up to date for certain mobile operators.

With these fixes and improvements, Microsoft has also disclosed a known issue.
This issue might be a headache for the IT admins who install this update..
If you have configured the FixedDrivesEncryptionType or the SystemDrivesEncryptionType policy to “Enabled” in the BitLocker CSP node in the Mobile Device Management (MDM), then the “Require Device Encryption” settings page on some devices may incorrectly show a “65000” error.
Affected environments are those with the “Enforce drive encryption type on operating system drives” or “Enforce drive encryption on fixed drives” policies set to Enabled and selecting either “full encryption” or “used space only“. Microsoft Intune is affected by this issue but third-party MDMs might also be affected.
Microsoft suggests setting the “Enforce drive encryption type on operating system drives” or “Enforce drive encryption on fixed drives” policies to “Not configured” to mitigate this issue temporarily, while they work on a permanent fix.

Block KB5031445 from installing

Download the “Show or hide updates” tool from Microsoft.
Run the utility and click Next to start the scanning process.
Next, click the “Hide updates” button.
Select the updates you want to block and click Next.
This automatically hides the update from Windows Update and it will not be installed during the next update process.

If you want to unhide or show hidden updates, run the tool again and select “Show hidden updates” instead of “Hide updates.” The rest of the process is the same.
