[MC-79635] Crash when opening world in any version using new Authlib (released with 1.8.4)

After updating to 1.8.4, the game crashes when I try to open one of my worlds. It did not crash in 1.8.3 or any other version, but since updating it crashes in all versions I have tried. The stack trace indicates that the crash was caused by the new version of AuthLib released with 1.8.4 (and included with older versions), so it seems likely that that is the cause. I've attached 1.8.3 and 1.8.4 crash reports, and uploaded the world. I'm sorry if this has already been reported, I searched but didn't see anything like this.

Caused by: java.lang.NullPointerException
