Can you please try to uninstall Kaspersky, restart, check if the issue is fixed for a while, then re-install it, restart and check again?

I'm Ugo, an Independent Advisor willing to help other Microsoft customers.
Regarding your question, by any chance, do you have a Kaspersky product installed? If so, kneps.sys belongs to it.
Please let me know if this helped somehow.
Ciao
Ugo
