I had a similar issue. I needed to disable the 'Windows Sandbox' feature - restart my computer and then the update was installed successfully!
Maybe this will help other people.

I have tried to update to 2025-01 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5050009) but i get the (Install error - 0x80070306)
I have restarted and shut down my computer multiple times to see if that would fix it but it didn't. I've also tried re-installing the update as well.
Please let me know what i can do to.

2025-01-21T16:09:08+00:00 So I did the same thing with installing files individually, got the same error. Then i went to advanced options and attempted to just wipe it clean with user files and i was stuck on retry for repair and not the update anymore. Before all that I also wiped out software distribution files and that didn't work. What worked for me was pausing updates and then resuming the updates. Now I don't have updates being stuck on restart.
