Scene Capture Cube: Render Not Unwrapped

Hello everyone! I hope you are all well. I have quite an urgent question!
I was creating fake rooms for my buildings, following this tutorial: https://www.youtube.com/watch?v=6XDUfCalSdE&t=1061s

All was going well, until I dragged my Texture Render Target Cube into my Scene Capture Cube’s Texture Target and saw the render. The 3D Map, which should look like an HDRI or an unwrapped cube’s UV, looks like a cube. I’ll attach an image.

I am not sure why this happened since I followed the instruction to the letter.

I’s really appreciate some help!

Thank you so much!
