Whenever I try to join/create a world, I get the "Invalid player data" message after loading chunks. This boots me out of the world immediately before even joining, making it impossible to play with this mod.

I have tried using dependencies closer to the release date of the latest version release, and it does not solve the issue.

I suspect the issue may reside in Geckolib's rewrite upon updating to 1.19.3, though the latest.log only mentions errors related to Kotlin. I don't know enough to tell though.

I have attached my latest.log since I've heard that helps
latest.log

Here are the mods I'm using:
