Bug Scenes displaying differently in build and editor

I am developing on the Quest 2.

Up to now, I had a strange problem where the first scene in the build would load normally, while when I loaded the second, this would mangle the global illumination (not using the mixed mode).

Now, I have straight up a problem with the first scene loaded.

This is the editor view:


This is in the Quest 2:


Keep in mind the particles shader there is just simple particles and I did NOT touch it at all for several days.

Other build.
3rd map in editor:


In Quest 2:


Sky lighting is gone.

Don't bother about the text on the Quest screen lacking in the editor, that is ok.

The fun part is that the first map in the build always loads correctly, except, now, the one shown up here that has some problem with the particles shader, but the global illumination is ok in the first map of the build.
