I am working on reversing the app built by Unity 2019.4.15f1 and I am using same version of Unity.
Using the AssetRipper tool, I get the project structure and asset files. But When I build the project on Unity, I get the some issues following as:
enter image description here
Most of issues are “AssetsPluginsAssembly-CSharp-firstpassPropertiesAssemblyInfo.cs(4,12): error CS0433: The type ‘RuntimeCompatibilityAttribute’ exists in both ‘mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null’ and ‘mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′”
