Hi there,

Local Security Authority Subsystem Service (LSASS) is responsible for security policy enforcement on Windows systems and it is used by the system to add entries to the security log, as well as to handle user logins, password changes, and access token creation.

You can try either of the workarounds provided below to mitigate the issue on your device
Uninstall the problematic update and block the update
Disable Fast Startup

There is also a hotfix 2998097 for this and you can get it from here
