To reproduce:

• Forge 1.20.1 server with BungeeForge, Proxy-Compatible-Forge, Mana and Artifice, Curios, Geckolib (the latter two being dependencies of Mana and Artifice)
• Forge 1.20.1 client with Mana and Artifice, Curios, Geckolib
• Velocity proxy with Ambassador and player-info-forwarding-mode = "legacy" in velocity.toml
• Connect to the server through Velocity; get kicked with nondescript errors on client and server, and the above stacktrace in Velocity

Note that Ambassador v1.5.0-rc-beta works fine, while v1.5.2-beta does not!

I just released 1.4.4 as version you can use in the meantime with the latest velocity.
