Windows update KB5013943 on Windows 11 makes all Affinity apps stop working

[Pandovski]

Cheers everyone.

As title suggest, today's stable update released by Microsoft for Windows 11 (Pro) made all of my Affinity applications stop working. All I get is error 0xc000135 when I try to open Designer or Photo. When I Google search that code I get that it's NET framework and compatibility related. However, from the 3 updates, installing or uninstalling the NET Framework ones dosen't affect Affinity. It still works as it should. I've narrowed it down to this cumulative KB5013943 update that causes the issue. If I don't install that one, everything works.

The compatibility troubleshooter did nothing useful, to no surprise. I don't know if this is specific to my machine, so someone else please chime in. Meanwhile I'm keeping that update paused from installing.

Hi @Pandovski,

Thanks for your report and I'm sorry to see you're having trouble!

Firstly, I have removed 2 screenshots from your post, as they contain the email address used for your microsoft account and I would not wish for this to be publicly available.

Secondly, I have installed this update here on my Win11 machine and the Affinity apps still load and run as expected for me.

Therefore I would like to request you run the following .NET repair tool, restart your system and then try running the apps again -

Does this change the observed behaviour please?
