Issue with older drivers for Nvidia display adapters (GPU)
Nvidia and Microsoft have found incompatibility issues with certain versions of Nvidia display adapter drivers and Windows 10, version 2004 (the Windows 10 May 2020 Update). Windows 10 devices with affected Nvidia display driver versions might receive a stop error with a blue screen or other issues during or after installing the update to Windows 10, version 2004. The affected drivers are any version lower than 358.00.
To safeguard your update experience, we have applied a compatibility hold on Windows 10 devices with affected Nvidia display drivers drivers installed from being offered Windows 10, version 2004 or Windows Server, version 2004 until the driver has been updated.
Affected platforms:
Workaround: To mitigate this issue, you will need to check with your device manufacturer (OEM) to see if an updated driver is available and install it.
Next steps: Microsoft and Nvidia are working on a resolution and will provide an update in an upcoming release.
Note We recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until this issue has been resolved.

Those would be older than Zwift itself btw. 
I just copy and paste that all from Microsoft’s website
