Can't install Update KB5025305

I am running WIN 11 pro on my main daily use system so I am only in the Release Preview ring.



I can't install "2023-04 Kumulatives Update für Windows 11 Version 22H2 für x64-basierte Systeme (KB5025305)" if I try I get initially error 0x800f031 and later on 0x80070002







I have tried the followings things then:



DISM /Online /Cleanup-Image /RestoreHealth

got stuck with an DISM error for missing source files 0x800f081f



sfc /scannow

ran through and seemed fixed something



Then I downloaded and mounted a WIN 11 ISO "Win11_22H2_German_x64v1.iso" and tried in CMD and Powershell with



Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:\sources\install.wim:5 /LimitAccess

5 is the index of win pro, but it stopped with not being able to find the source/file eventhough the path is correct



Lastly I tried:



DISM /Online /Cleanup-Image /RestoreHealth /Source:wim:\Sources\install.wim:5



Which stopped again with 0x800f081f



I also tried to install

windows11.0-kb5025305-x64_fe30588ba820ad206f75ccd21977d2f8e92319ef.msu

which did not work neither



Cleaning up the Download Files and the Data Store File for the update and trying



DISM.exe /Online /Enable-Feature /FeatureName:NetFx3 /All



none of this worked.



In System / Windows Update the download will always begin and at some stage the install will begin, it goes to 50 / 51% then it all of a sudden jumped to 100% install but the end with an error 0x800f0831.



When restarting the machine the next time, the black windows update screen will appear, but not percentage, the screen will stay on for some time unitl the machine reboots finally.

So it looks like something would be updated indeed, but nothing happens, also the update will appear again in system / windows upate after that.



Can somebody please help me out please, how can i get the current update or a later one?
