Microsoft released updates for its Windows operating systems on April 2022 Patch Day. The company didn’t highlight any major issues in the release notes, and installation appears to have gone smoothly on most devices.
Some users report that they can no longer launch popular web browsers after installing the latest Windows updates. The error message “the application was unable to start correctly (0xc0000022)” is thrown on these devices, and the problem seems to affect browsers such as Firefox, Chrome, and even Microsoft’s own Edge browser.
Reports suggest that the issue does not affect all browsers, and users who are affected by it may want to try other ones, for example, Brave or Vivaldi, to see if those can be launched. Uninstalling updates, for example KB5012599, fixes the problem.
A search of Microsoft’s Feedback Hub returns multiple reports of the issue. Some reports were released in the last 24 hours, but others were released months ago in Insider builds.
After installing KB5012599 I got error 0xc0000022 when launching Edge, Firefox and Chrome, so they no longer work. Luckily, Vivaldi and Brave work perfectly, so I can still access the internet.
Uninstalling KB5012599 resolves this issue.
The low number of reports on the Feedback Hub suggests that the issue may not be widespread. Still, some users report crashes after installing updates.
Reports suggest that Windows 10 and Windows 11 devices are affected by the issue. Microsoft has yet to respond to the complaints.
Although this seems to be a problem caused by the latest Windows updates, some suggest that anti-virus products could also play a role. Windows Latest specifically mentions ESET, but it’s possible that other antivirus solutions are also causing the problem.
Affected users who have to use crashing browsers may need to uninstall the update to resolve the issue.
