Issue with building for Windows

Hello, I have a very strange problem.

Currently I am developing an app that should network between the PC and an Android device. So far everything was tested in editor and worked fine.

Now today I wanted to compile the project and build it. The building process was going fine and completed, but as soon as I opened it it crashed with Unknown Error. Later I went to check the logs and this is the output.

Please help me resolve this issue because i haven’t found not even 1 instance of a simillar one.
