Every time Microsoft releases a new update for Windows it fixes various bugs in the operating system, but creates new ones. And lately, it seems that the company does not finish finding the key, and the number of users with problems using Windows after each update is constantly increasing. Now, after the last update, the ones who are running into a lot of problems are the players. And the fault seems to be related to Discord.
Discord is a widely used chat platform in the gaming world. This platform is used both to broadcast and to be in contact, by video, audio or text, with our fellow players. It is considered an essential tool for any player.

Unfortunately, in the past few days, there have been a large number of users who have encountered a Direct3D 12 error when trying to run certain titles on Windows 10. Games close silently, without a warning message, or with an error. The games that usually give errors are those that use DirectPlay technology, as is the case with Word of Warcraft, a very popular game in streaming.
Discord is not compatible with the latest Windows 10 update
After much research, and many headaches on the part of players, it seems that the problem lies in a compatibility problem between the KB4598291 patch and Discord’s Overlay mode . We already warned two days ago that this update was going to be very controversial. Especially when its changes become part of the cumulative patches released on February 9, 2021.

After adding dozens of complaints, Microsoft got to work until, finally, it has found the cause of the problem. A compatibility flaw introduced with the latest Windows quality patches causes games to crash or crash when opened with Discord overlay mode.
The bug appears to affect all users of Windows 10 versions 1909, 2004 and 20H2. Earlier versions (such as 1903 and 1809) do not appear to be affected.
How to troubleshoot
The quickest thing to do would be to disable Discord’s overlay mode so the games could run smoothly. Temporarily we can turn to another PC, a tablet or a smartphone to have the chats at hand until Microsoft and Discord solve this problem. Another much more radical solution is to uninstall the program from the PC, making the games work without problems again.
Discord claims to have released a new update to the tool that makes everything work normally again. Therefore, we can search for new versions of the program from its main window to install the latest version and be able to use the program again without problems.
In any case, we remember that the KB4598291 patch introduces many more problems than it solves. Many users experience blue screens and performance drops after updating. Therefore, if we experience any of these problems, then it is necessary to uninstall the problematic update from the PC so that everything works normally again.
