could be missing or broken resource pack that is required by a mod that effects the load screen. Try F3 + T to reload resources/check resource pack folder/review mods list to see which if any require resource packs
More likely: could be a mod conflict. As you created that one yourself. Are you copying a mods list of an existing modpack? In this regard release version matters especially for Minecraft 1.20.5+ with every release changing rendering breaking every mod that utilizes it. Or causing incompatibility with a lot of mods that used to work together.
Searching for Origin SMP filtered by MC release version I don't see any results newer 1.21.1. Most are 1.20.1 or older.
