3. Open the script UnionGenerator.cs
4. At line 193, insert the two following lines of code: var hash = new System.HashCode(); hash.Add(0);
5. Save the script file
6. In the Project window, navigate to Assets -> Examples
7. Select the Asset "UnionGenesisSettings"

- Crash on BaseHierarchyProperty::Next when opening a specific project
- Shader Compilation for projects with lots of Shaders can be slow (i.e. VFX Graph asset heavy projects)
- The Editor hangs when opening a project that uses local packages and Version Control
- Area Light is culled when Camera Frustrum is outside the lights range
Resolution Note:
.asmdefs with platform "Editor" only are always compiled against the .net framework profile. To solve the issue, the .asmdef platform should be set as "all platform", and use a define constraint to avoid having it deployed with player builds (adding "UNITY_EDITOR" to the list of define constraints). This way, Unity will compile it as a .NET standard 2.1, and both the Mono runtime and .NET core will succeed in redirecting "System.HashCode, netstandard" to its correct implementation.
