[Bug] Error when assigning spells to classes

[crash1115]

In the spellbook tab, clicking on Tools > Assign Spells to Classes produces an error and doesn't let you assign spells to classes.

Foundry v12.331 dnd5e v3.3.1 Tidy v5.6.2

I can't repro, unfortunately. Can you check to see if this is possibly a module interaction or some data-specific thing that needs accounting for?

When I do this from my dev world, I'm not seeing an error with a spellcaster:

Even a nonspellcaster like Randal doesn't have issues:

I'll try to follow up this evening, will post my findings shortly!

So I've tested on:

• My dev world and a fresh world (self hosted on win 10)
• No other modules enabled
• Both running the versions listed in the original post
• As both a GM and a player
• On the Foundry app, Chrome, and Firefox

In every combination of those things, it's happening to every actor in these two worlds. That includes:

• Preexisting actors that have been imported from other worlds (and may have weird data baggage)
• Freshly imported starter heroes (with no weird data baggage, theoretically)
• Actors created from scratch with nothing on them
• Actors created from scratch with wizard class and evocation school subclass dragged from SRD compendium

This happens regardless of whether or not the actor has any spells in the spellbook. I tried messing with the class' spellcasting settings - half caster/full caster/etc and spellcasting ability - but no dice. I tried with and without spells in the spellbook. I tried with and without spell slots. None of these things appeared to make a difference.

EDIT: Reinstalling Tidy did not make a difference.

I tested on a completely different wold, not hosted by me, where I'm a player, and things seemed to work fine. Go figure, lol.

I've attached a few actors for you to take a peek at, but if you need to jump into my world, shoot me a DM on discord whenever you have time to take a look, and I can get you login info.
