Detailed description：
I can't turn on the Core Isolation - Memory Integrity.
I only saw this error after doing Windows update recently and using Mumu Player which is a PC Emulator by Netease.
I contacted Microsoft Support and there is still no update fix for it. I saw online that the usb2ser.sys by MediaTek is from Asus. Need help.

johnpaultan07@johnpaultan07Update: Today I updated my Windows 11 to the latest version 22H2. Now the Windows Security is showing ok and it's not flagging Core Isolation anymore. But I still can't turn on the Core Isolation because of the old Mediatek driver usb2ser.sys

As in the previous reply to you, this model is not shipped with MKT network card, if you have no impression of connecting other devices, we would recommend that you back up your data and restore the system. Sorry for any inconvenience it may be caused.
@Falcon_ASUS After I did few more Windows update after updating to the lastest version 22H2 the Core Isolation issue is getting flagged by Windows Security again.

This is the picture you provided earlier, it is described that the problem may be caused by the MKT device.
If the situation persists after the system update, we would recommend that you back up your data and restore the system.

@Falcon_ASUS right now I contacted ASUS APAC support trying to update the BIOS firmware as Microsoft Engineers said it could fix the core Isolation issue. But ASUS APAC support still don't have an answer since when I try to update the firmware to X509DA 309 but my system firmware says X509DAP 302.
