Since version 'Forge-1.20.1-1.23.2' there is an inability to craft any item related to the mod. Using such tools as JEI, left-clicking to reveal recipes does nothing. Spawning items in via creative works just fine, and items function as intended. Attempting to craft items in the crafting bench via memory (this mod has been around for a while =P) yields no results.

Sadly, I cannot reproduce this issue. Are you perhaps using some other mods?
For example, Forgified Fabric API had an issue that caused this until I fixed it over at their end (Sinytra/ForgifiedFabricAPI#204) - you will need to update that mod to the latest version to fix this issue.
If you don't have that one, could you please post some log file or a mod list here? :)

I use a custom modpack, so there are tons of mods (199 atm) Here is the latest modpack code from curseforge: 2wp9CxvH (valid for 1 week of this post). Let me know of any known conflicts and possible remedies, thank you!

Your modpack contains Forgified Fabric API:

Its version is too old - I fixed the recipe bug in this release:
https://github.com/Sinytra/ForgifiedFabricAPI/releases/tag/0.92.2%2B1.11.12%2B1.20.1

The mod providing FFAPI is "TxniLib", which is outdated in your modpack.
Upon updating it to the newest version, the recipes work fine.
