Microsoft and Lenovo are working on an update to prevent Windows 10 from crashing on ThinkPad laptops. A recent update to Windows 10 caused os issues on ThinkPad models from 2019 and 2020, including blue screen of death-crashes.

Microsoft acknowledges that ThinkPad users who KB4568831 update or subsequent windows 10 updates may run into problems. Those problems may occur if the systems have Enhanced Windows Biometric Security enabled in the UEFI and run Lenovo Vantage software.

The ThinkPads can then give blue screen of death crashes during startup and while starting Lenovo Vantage or Windows Defender Scan. Also, login with facial recognition via Windows Hello is not possible. Users get the ‘System_thread_exception_not_handled’ and ‘0xc0000005 Access Denied’ error message in crash, belonging to process ldiagio.sys, microsoft.

The cause lies in how Windows 10 restricts how processes access pci configurations of devices after the update is implemented. When Lenovo is running Vantage, ThinkPads can attempt to access PCI configurations in a way that is not supported, resulting in crashes.

As a temporary workaround, Microsoft recommend and Lenovo to disable Enhanced Windows Biometric Security in UEFI. This option can be found in the virtualization section of the Security page in the UEFI. It is not known when the fix will be ready
