The issue appears to affect apps that use the .NET Framework. As Windows Latest reports, users have complained about the following programs via Microsoft’s Feedback Hub:

The bug doesn’t affect all users of these apps, but if you see this error message, you’ll know what’s causing it: “The application was unable to start correctly (0xc0000135). Click OK to close the application.” As a result, it’s worth holding off installing the update if you haven’t already. It’s technically mandatory, so may be automatically downloaded in the background, but installation requires a restart which you can avoid. Microsoft is yet to release a fix, but two unofficial fixes may solve the issue for you.

While we wait for an official patch, another potential solution is available. The bug appears to be caused by a compatibility issue between Windows 11 and the .NET Framework, so reinstalling both version 3.5 and 4.8 should solve the problem. Here’s how it’s done: If that doesn’t work and the app crashes are proving very disruptive, you can also uninstall the update completely. However, this process will only work if you installed it today or yesterday: If that doesn’t solve the problem either, it may be caused by the earlier optional update where app crashes were first reported. In that scenario, or if more than a day has passed since you installed the update, you’ll need to wait for Microsoft to release a patch.
