Hololens and Transport layer || Unable to load plugin `network.bindings.dll`

Hello,
I am trying to create a online application with the Hololens.
I am connecting multiple platforms such as Android, Windows standalone and the Hololens.
The transport layer works perfectly on Android and Windows standalone. But the Hololens keeps giving me errors saying that it can not find the dll or it's dependencies, but the dll is present in the file-directory of the build.

The Hololens will build and run the app, but as soon as I activate the "client" it gives me the following errors:
'MultiplatformManager.exe' (Win32): Loaded '[Directory...]network.bindings.dll'. Symbols loaded.
'MultiplatformManager.exe' (Win32): Unloaded '[Directory...]network.bindings.dll'
Plugins: Failed to load 'network.bindings' because one or more of its dependencies could not be loaded.
Unable to load plugin `network.bindings.dll

I also tried rebuilding the dll as 86x, but that did not help either
And yes, the settings in Unity are correct so that the dll is to be included in the WSAplayer.


I am not sure what to do, hopefully someone can help!
I included the full error.

Greetings,
Max
