Flickering in materials with alpha opacity

Please, does anyone know how to fix the issue of a material with alpha opacity flickering when it enters the scene through the camera? Thank you in advance!

Here is a clip showing some parts where this issue occurs.

Could you please be more specific of the issue? I watched it few times and I’m not sure where something enters the scene through the camera.

If you look at this image, you will notice the issue where the material disappears at certain angles.
