Render (TTY) error

hello everyone! I have a big patch with a lot of error on the TTY, which ones are really problems? also, how I can trace where exactly is the problem (which node)?

here some examples:

00:00:01 ERR : System.IO.FileLoadException in mscorlib: API restriction: The assembly ‘file:///C:\Users\Nicola\Desktop\vvvv_45beta34.2_x64\packs\dx11\nodes\plugins\Gma.QrCodeNet.Encoding.dll’ has already loaded from a different location.

00:00:21 ERR : There is no common media type between these pins.
00:00:21 ERR : The operation cannot be performed because the pins are not connected.
