Error related to System.Xml while installing the game after deploying it

After I did some stuff I wanted to deploy it, just to try it out you know? Then when I tried to install it on another machine (even on the same one I did the deploying after that) I received some sort of error:

Following errors were detected during this operation.
* [07/10/2017 20:30:05] System.InvalidOperationException
- The ‘EndValidation’ method cannot not be called when all the elements have not been validated. ‘ValidateEndElement’ calls corresponding to ‘ValidateElement’ calls might be missing.
- Source: System.Xml

The entire log can be viewed in this pastebin:

Does anyone know what is causing this?

I am currently having the same issue - did you ever get it resolved? How?
