Questions & Answers

Yeah so this has started to happen with Unity 2018, and in every single project be it upgraded or brand new. These errors are not game breaking, but i simply hate to have em pop up in every single project.

Unable to parse file ProjectSettings/ProjectVersion.txt: [Control characters are not allowed] at line 0

TargetException: Non-static method requires a target.
System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:236)
System.Reflection.MethodBase.Invoke (System.Object obj, System.Object[] parameters) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MethodBase.cs:115)
UnityEditor.EditorAssemblies.ProcessInitializeOnLoadMethod (System.Reflection.MethodInfo method) (at C:/buildslave/unity/build/Editor/Mono/EditorAssemblies.cs:116)
UnityEditor.EditorAssemblies.ProcessInitializeOnLoadAttributes () (at C:/buildslave/unity/build/Editor/Mono/EditorAssemblies.cs:135)

Help would be appreciated. As i said above, not game breaking errors but i want to get rid of them.

You can vote for the issue to be fixed here: Unity Issue Tracker - Merge conflict in ProjectVersion.txt causes 'Unable to parse file' error on any project opened

From te issue tracker voting page linked above:
“Workaround: This issue is likely a merge conflict in one of the ProjectVersion.txt files. The error is still present on any new project opened, so for now, it is suggested going through the projects and finding the one ProjectVersion.txt file causing this and deleting it.”
It works.
