DR Studio 17.4 not working on windows 10 Pro

I have upgraded to all prior releases with no issue but DR crashes on opening with 17.4. I have reverted to 17.3.x and it works again. FYI. Here is the error:

In the Resolve Help menu, select "Create Diagnostics Log on Desktop"

This will place a Resolve log file named similar to this on your Windows desktop: DaVinci-Resolve-logs-20181228_140434.zip (You may not see the .zip extension if your system is set to hide known extensions).

Then open Windows System Information and do a File - Save (Not a File Export), which will generate a .NFO file.

Place both those files on a file sharing site and provide links to the files here.
