Hello @Rawad Alahmdi, 

Welcome!
Issue is supposed to be fixed by MR3.

1. Which version do you have:  on the Windows Taskbar or hidden icons, rightclick the Kaspersky icon, select About? 
2. IF it’s v21.1 or 21.2, clean install to v21.3 & retest?
3. IF 21.3 is already installed, do the following, as requested by @Anton Mefodys, ref topic klflt.sys failed - Windows 10 crashes (code: DRIVER_IRQL_NOT_LESS_OR_EQUAL)

Set the OS to collect full memory dump: https://support.kaspersky.com/common/diagnostics/12402

Reproduce the issue one more time.
