Hello,
I've been having this issue for a while but now I'm trying to actually fix it. I couldn't install 24H2 when it first released due to this issue and now it seems, despite the posts I've been seeing of Microsoft removing the blocks from EAC affecting this update, I still cannot install it or 25H2.
I've attached an image of the error I'm seeing when I try to install 25H2 (error code: 0xc1900209). I've updated my BIOS and I've tried uninstalling all the games I own that have EAC (Overwatch and Marvel Rivals) and I'm its still not working. I don't know if it's helpful, but my specs are below:
OS: Windows 11 Pro (currently on version 23H2)
