Reasons behind Windows Defender crashing in Windows 11/10 and their Relevant Fixes
Windows security forms an integral part of your windows PC and is the first and prime layer of defense.

If a software bug comes up in the Windows preview build breaking the operating system, you will get the message ‘ you will need a new app to this windows defender link’ on your Windows 11 PC. A similar problem is also common to the 2004 build version of Windows 10.
Pirated Windows– It is another reason behind the windows defender crashing. Unfortunately, all products of Windows are highly expensive, and people tend to find some easy solutions for free. Microsoft indeed made a great decision to offer the free version of windows 10 edition in 2015, but many of the users ended up ignoring this free version. Instead, they ended up installing pirated windows in their system.
Windows Threat– Windows software ended up witnessing over 200 million malware chunks in 2020. A powerful malware can infect the system and disable the security system to make the software highly vulnerable. You should reinstall the OS to get rid of the malware and solve the issue.
Corrupt Windows System Files– Windows do end up facing software corruption. And this problem is quite common, where you need to simply learn how to scan your system for the corrupted files and get rid of them.
Third-Party Antivirus– Windows Defender was recognized as a unique selling nib. The world has evolved drastically with technological advancement, and today Microsoft has managed to cover up the shortcomings that Windows Security had and, in turn, has accepted the entry of any third-party antivirus within the system. Now the responsibility of Windows Defender is handed over to the antivirus system. And this could be a reason why the Windows Defender is crashing in windows 11/10.
