Too many Unspecified Errors!

I get so many of these errors in my Output window (redirected to Immediate) that just the time to output them onto the screen is slowing down my app development and debugging. How can I get rid of these meaningless errors or at least prevent them from showing up in the Output ?

I am using WindowsAppSDK 1.6 with VS 17.12.

Msg:[Failed to set process redirection guard from DisableMitigations]

Start by reproducing the reported output with WindowsAppSDK 1.6 and Visual Studio 17.12, using the listed Microsoft.ui.xaml.dll, Microsoft.Internal.WarpPal.dll, dwmcorei.dll, and Windows.Storage.ApplicationData.dll messages as the investigation points. The issue names no application code, test, or expected fix, so done would require identifying the cause of the repeated errors and documenting a verified way to eliminate or prevent them.
