That's not the crash report, there is nothing I can get from that unfortunately.
Though the versions of my mods do work fine by themselves on the latest NeoForge, so I'd assume there is another mod causing you issues here, likely JEI.
Honestly ideally I'd recommend downgrading NeoForge to 21.5.72 and Puzzles Lib to v21.5.10.
NeoForge 21.5.73 contains an unnecessary breaking change which causes many mods to crash. So until they've had more time to update just stay on the older version, you are not missing out on anything.

yeah I just downgraded and I asked ai as to why and I made a temp fix I was on neoforge 21.5.72 and when loading in would cause an error due to level range restriction deep seek helped me find a temp fix to edit the toml file Analysis of Your Latest Log
The crash is caused by a version parsing conflict between PuzzlesLib and NeoForge, despite both being at version 21.5.72. Here's the critical error:

log
[main/ERROR] Missing or unsupported mandatory dependencies:
Mod ID: 'neoforge', Requested by: 'puzzleslib',
Expected range: '[21.5.72,)',
Actual version: '21.5.72-beta'
Root Cause
Version String Mismatch
PuzzlesLib v21.5.12 requires NeoForge 21.5.72 exactly (without the -beta suffix) due to strict version checks in its mods.toml.

NeoForge's Beta Tag
Your NeoForge installation identifies as 21.5.72-beta, which PuzzlesLib rejects as "unsupported".

Conflict Chain Reaction
Since PuzzlesLib is a dependency for 14+ mods in your pack (like EasyMagic, VisualWorkbench), its failure cascades through all dependent mods.
