VPN driver issue

If I'm not mistaken, kltun.sys is the Kaspersky VPN driver, correct?

Since a couple of days I'm receiving the error as presented in the attached screen.

If I follow the guidance and disable to core isolation, it's gone, but once I re-enable it, the error is back. Is this an issue with Kaspersky? Can someone help with this one?

Can you post version of operating system and KVPN?

Oh, right... Win 25H2 26200.8246 with Kaspersky Plus 21.24.8.522(b).

Hum weird... I have KVPN also in a W11 Pro 25H2, with all the Core Isolation options enabled, and not getting that issue 🤔

Clearly the same version as I have... 🤨

I've run SFC and DISM to see if any system elements might be corrupted but apparently not.
