Windows Stopped updating and failed to install updates

Okay so after more then a week i fixed and solve the problem

here is what i think has gone wrong:

i think windows ha failed to Install Security update kb5124008

this update was not shown in the update history

windows security update kb5129195 kept failing to install and triggerd a Windows restore, so it kept downloading and installing windows 25H2 (restrore) and that kept failing to install after a restart after downloading and installing it kept saying it failed to install

Same goes for the Security update kb5124008, that kept downloading and failing to install but there was a massage under it that made me wondering it was soimething like: "because missing previous update this one can`t be installed) 

so i downloaded the kb5129195 from windows catalog site, that kept failing too 

so after days trying and sharing here on the page what i was doing i just wondered what the security update before this one was and it was Security update kb5124008

so i thought, what if i just reinstall that one with the catalog file, if that one was somehow corupted, because this update was no where fount in my already installed updates. 

(in the mean time i had alrady downloaded the security update before this ona and that said it was already installed but i think because of the delayed updates of windows i mixed the dates up)

so i installed that one (Security update kb5124008) and for the first time in days an update succeeded. 

and i restarted the pc and immediately went to windows updates, and it was scanning for updates and it installed a windows defender update and it finally said: no more updates

From that moment on i also tried to do a backup because during all this trouble no image backup or all backups where failing because it saw a bad file during the backup progress 

it took me nights and days to get to the point each time to come to the conclusion backup my files was impossable. 

but after installing Security update kb5124008 it fixed everything and i was able to backup my pc again 

i still sdont know for sure what went wrong. i Think i shut down my pc while installing the update kb5124008

or kb5124008 fixed something a update before that has caused a problem what prevented me to update and backup anything. i still dont know but this is what i did and what helped me fix my pc
