[Forge 1.19.2] [Bug] Strange bug won't let me enter my world due to "invalid player data"

[vizthex123]

What happened?

Not sure what's causing it as the mod works fine on my other 1.19 packs, but this one's got this weird issue.

Creating a new world also returns the same error, as does downgrading to 9.2.779.

Here's the full log where I enter my existing world, then create a new one after it fails:

Anything else?

I replaced JEI as part of an update to the pack (since I vastly prefer REI). Even disabled the CraftTweaker script just in case.

By submitting this issue, I have included the necessary logs by pasting the contents into the correct location or attaching the file as an upload.

• Yes, and I did not use any paste services other than GitHub Gists.

By submitting this issue, I have confirmed my REI and REI's dependencies are up to date.
