0x8007000d error Windows 10 IIS 10

Getting the error below, tried a couple different website publishes from Visual Studio 2019, I first set up a website through IIS pointing to a folder in inetpub\www\xxxxx

I've completely uninstalled IIS and reinstalled.

Any ideas?   the error is saying it's a webconfig problem, but I've published more than 1 site so I don't think it is application specific issue, seems to be an IIS issue on this local machine... 

These are .netcore 3.1 applications.  because the apps work via iisExpress, I must have all the frameworks/sdks I need...
