Error Unable to find player assembly

I´m doing a Unity 3D game and when I went to do the build this error appeared on the console:

Unable to find player assembly: Library/PlayerScriptAssemblies/UnityEngine.TestRunner.dll
UnityEngine.Debug:LogWarning (object)
Unity.Burst.Editor.BurstAotCompiler:OnPostBuildPlayerScriptDLLsImpl (Unity.Burst.Editor.BurstAotCompiler/BurstAOTSettings,UnityEditor.Compilation.Assembly[]) (at Library/PackageCache/com.unity.burst@1.8.2/Editor/BurstAotCompiler.cs:498)
Unity.Burst.Editor.BurstAOTCompilerPostprocessor:DoGenerate (UnityEditor.Compilation.Assembly[]) (at Library/PackageCache/com.unity.burst@1.8.2/Editor/BurstAotCompiler.cs:265)
Unity.Burst.Editor.BurstAOTCompilerPostprocessor:OnPostBuildPlayerScriptDLLs (UnityEditor.Build.Reporting.BuildReport) (at Library/PackageCache/com.unity.burst@1.8.2/Editor/BurstAotCompiler.cs:189)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&). 

The build succeeds, but when I open it, it loads the Unity logo and closes.

After I read some people saying to disable the burst AOT, when I did the error stopped appearing but the build doesn´t open anyway.
