Everyone surely remembers the latest Windows 11 Insider build. We covered it only a few days ago, and yes, we are talking about KB5012643.

We all made ourselves familiar with all of the benefits that the software brings, and rejoiced in knowing that there was only one, small known issue.

However, little did we know that the update has also introduced a new bug into Windows 11 systems, one that makes the screen flicker when a user enters the Safe Mode.

Entering Safe Mode will make your screen flicker

Now, surely Microsoft didn’t plan this, but it also didn’t expect it, which kind of speaks for itself about the quality of some of the products we receive from the tech giant.

Let’s just say it’s not a machine-frying issue, but users did get horribly frustrated when noticing what else came packaged with build 22000.652.

That being said, now that this has become public information, the Redmond-based tech company will have to start working on a solution.

Now, don’t go thinking that this is the end of the world, as some of the more tech-savvy users have already provided a workaround to this problem.

Apparently, if you are going to use 5 or F5 instead of 4 or F4, the problem seems to go away, leaving everything as it once was.

Until the problem is dealt with, we suggest not installing this latest build if you have to use Safe Mode to conduct your daily business.

However, if not installing it isn’t an option, we can show you how to get the update on your device in just a few seconds.
