Unity does not complete build

The game I am working on has no problems while I play it in the editor, all the scripts are working fine. But when I build it (for TIZEN btw) as soon as the building process reaches “building list of referenced assemblies” the building process stops right there. There no no build file either.
Any help is appreciated.

Same here > trying to build for iOS but stops at

“building list of referenced assemblies”

With the error:
AssemblyResolutionException: Failed to resolve assembly: ‘UnityEngine, Version=, Culture=neutral, PublicKeyToken=null’

I am using Unity 5.5.0f3 for this one particular project.

Have you found a solution @nikrath ?
