Malex17 I found a workaround in the topic at Reddit and confirmed it fixes the issue. 

 

I downloaded Windows 10 22H2 from October, created an Operating System Upgrade Package in SCCM and used this image for the upgrade. I then applied all my language packs in the TS (EN, NL, FR), rebooted the machine and then applied the LCU (Latest Cumulative Update) which in this case was KB5021233. After applying the patch and rebooting the pc, the Windows Defender Firewall is working fine again when the pc boots with NL set as system language.

 

I have now started a new test with the 22H2 from December and the LCU from Januari (KB5022282).

    Meanwhile I've got an answer from Microsoft Support. This issue should be fixed with the December Update.

    I've tested with KB5022282 (post-install) on 21H2 and it seems it's fixed.

    I will do another tests with an updated Image.

      I noticed something similar. When I install the update it works. However when I download and install e.g. the January image, which means no Windows CU updates are installed, it doesn't work on my side.

        I've exported the Updated Language packs (Get-AppxPackage -AllUsers -Name *lang*) with this script https://github.com/mjmeans/Appx-Backup (the script does not export the license.xml, you'll have to copy it manually) and imported them into the image.
        That seems to be the trick.
