Rendering only part of the scene, the rest in transparent

Hi Everyone!
I have a problem with this build.
In both: viewport and after rendering, it shows transparent lines on the background.
It looks like it only rendered space around the world origin.
I have created another camera, another texture: same effect, but the “cut” from a different angle.

As a new user I cannot upload attachments, so here is the link to the build and renders:

After rendering the video of the animation, I can see that on the last frames (after the sunrise) everything is perfect, and the scene is fully rendered after frame 380. Seems like I haven’t “frozen” some lights on the first frame. Is there a way to see the the keypoints by item?

Thank you!
