Found the problematic mod: Exordium
After removing Exordium I can now freely use the hotbar.
However, Minecraft still randomly crashes.

So I was looking to rebuild a modpack I was making to play it with my friends, and while adding some new mods, I encountered an issue where the hotbar would not update and was stuck on the same slot, however by using the scroll wheel I could still scroll through my items. Additionally, when removing the mod "Create: Copycats+" the hotbar completely disappears.

Forgot to mention that this happens also when I start or try to enter a singleplayer world.
Just resolved an issue where a mod called Impactor made a error appear saying: "File Mod File: failed to load a valid ResourcePackInfo"
Forge 1.20.1-47.2.17
I did as I usually do and take out sections of the mods in my mod folder at a time and I just now got a change
The error disappeared when I took out G through Q.
About to do some more testing to see what mod is causing the problem.
