Property (_AdditionalLightsColor) exceeds previous array size (256 vs 32). Cap to previous size. Restart Unity to recreate the arrays.

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Why do we need to restart our editor? Imagine you freshly opened a heavy project that takes minutes to be loaded. Why can't Unity recreate this array at runtime? In 2021, where mostly everything triggers a "Reload assembly" this should not be impossible.

 

Nothing the editor can help unfortunately. It's the graphics driver that allocates the memory on the GPU. Changing the size of an already allocated array requires reinitializing the graphics pipeline entirely, which is why a restart is required.

My guess is that this happens quite unintentionally. Possibly when switching target platforms?

This is also part of the reason why you have to restart some games when changing certain graphics settings.
