ReflectionProbes sometimes break when Update Mode is Always

Tested versions

• Reproduceable in: 4.4.stable

System information

Windows 10 - Godot v4.4.stable - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 2060

Issue description

When a ReflectionProbe has "Update Mode" set to "Always (Slow)", it sometimes will heavily lag and spam these 2 errors in to the console:

E 0:00:01:431   framebuffer_create_multipass: All attachments unused.
  <C++ Error>   Condition "!size_set" is true. Returning: RID()
  <C++ Source>  servers/rendering/rendering_device.cpp:2877 @ framebuffer_create_multipass()

and

E 0:00:01:432   texture_create_shared_from_slice: Parameter "src_texture" is null.
  <C++ Source>  servers/rendering/rendering_device.cpp:1211 @ texture_create_shared_from_slice()

It seems to have no trigger, its random when it will happen. If you have the bug happening, and you reload the project, the errors will happen with the Godot editor

Steps to reproduce

• Create a Reflection probe
• Set "Update Mode" to "Always (Slow)"
• Mess around with project rendering settings and play the game each edit until the bug happens

I tried adding a ReflectionProbe with Update Mode set to Always to the Platformer 3D Demo and ran it with a variety of project rendering settings with no issue. Are there specific rendering settings that cause it? Is it possible to trigger without running the game?
