Sun and moon disappeared

I don’t know the exact steps to reproduce the bug, but i will explain what happend:
I was playing in this world, that was with the gamerule “doDaylightCycle: false”, so it was always day. I went to dinner, but i left the game running. When i came back, the world was darker, and the sun was gone. I tried re-enabling “doDaylightCycle”, but i didn’t work. I tryed rebotting the game, but the bug persisted. Other world have the sun and moon just fine.

The expected result is the sun and moon to just disapear

I attached a video of the world and me trying changing the day time and the world folder as a zip.
