Maybe I know what happened. Did you opened GeoSpatialArf5 scene but and didn't have ARCORE_USE_ARF_5 defined then saved it.

The arf5 scene uses arf5 types from the sample code. These types only exist when built with ARCORE_USE_ARF_5 define. When Unity sees a value in the scene that it does not understand when you reserialize (ie you save) these new types become null.

Unfortunately when you don't define anything the sample code will default to ARF4.

To fix this situation.

  1. Start a new project using the arcore samples as your old scene file is corrupted.
  2. Do these steps before you open any scene (or at least don't save them)
    https://developers.google.com/ar/develop/unity-arf/update-to-ar-foundation-5
    The important bit is setting ARCORE_USE_ARF_5.
  3. Then use the Geospatial (or other arcore) samples like you would have before.
