The problem manifests itself only with your mod and the use of this texture pack:
KSEPSPv8.2-F0RZEL.zip

Version Minecraft: 1.20.1
Version Continuity: 3.0.0-beta.3

You did not provide your mod list but realistically the only way this could happen is if you did not install Indium. Duplicate of #107.
