The error code which you have provided is related to Windows defender. Have you updated all drivers? Also try to do a "hard Reset" by disconnecting the main battery, rtc/bios battery and ram, leave them disconnected for 15 min and reconnect as you might have a frozen Souper IO chip or bios chip ab]nd all this will rest both. If that doesn't work then follow these steps which should fix this issue:

Method 1:

If you have any third party antivirus software and firewall disable them temporarily and make sure that the Windows Firewall is turned on. Then check if the issue reappears.

Method 2:

1. Press Windows + R and type in services.msc then press Enter.

2. In services window, locate Windows Defender service in the services list.

3. Verify that the Status is Started. If the Status column is blank,

right click on the service and select Start.

4 If you get error trying to force start the Windows Defender service, try to change the Startup Type to Automatic, and then restart the computer.

5. Next you can download an Windows updates and check the issue.

You can refer to the Microsoft article and check.

Also, there is another issue if you are using Win-11 with "license will expire soon" that I've had with these warning, but this is a different error number and it fixed itself.
