Fresh pull won't work properly, various errors and spanish is set as default language.

A fresh pull doesn't seem to work, using Unity 2021.3.31f1 (LTS)

We keep getting post processing errors
```
Missing shader. PostProcessPass render pass will not execute. Check for missing reference in the renderer resources.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
```

and the game keeps starting in Spanish and doesn't want to continue from there.
