Hi when i tried to built my game it gave very weird error about assembly and dll things i was building as development build i disabled it and now i get this errors

Library\PackageCache\com.unity.inputsystem@1.5.1\Tests\TestFixture\InputTestFixture.cs(168,29): error CS0117: 'InputSystem' does not contain a definition for 'Restore'


UnityEditor.BuildPlayerWindow+BuildMethodException: 3 errors

I tried to remove the restore and savereset line after that it gave this error

ArgumentException: The Assembly nunit.framework is referenced by Unity.InputSystem.TestFramework ('Library/PlayerScriptAssemblies/Unity.InputSystem.TestFramework.dll'). But the dll is not allowed to be included or could not be found.

I tried to remove and reinstall the input system version 1.5.1 no change

I tried 1.5.0 version no change

 

Okey I solved the problem i guessed my unity editor version does not support 1.5.1 version with a little research i found that 2019.04 version supports 1.4 and before versions

 

Thanks kader1081! Just had the same issue and was looking everywhere for some answers.. Downgrading to 1.4 helped.
