I downloaded the 1.16.5 version (running 1.16.4). And noticed the following issues:
-Textures don't load in the player inventory.
-Placed models don't load.

The mechanics seem to work and not be affected.
Below you'll find some images to elaborate the issue:

  [21:27:41] [Worker-Main-13/ERROR]: Could not find Renderer API implementation. Rendering for RSWires wires will not be available.

You have Sodium installed, that doesn't provide a Fabric Renderer API implementation. Try installing Indium which should fix that.

Sorry for the late response!

Thank you! that fixed it.

Alright, nice.
