Describe the bug
With certain cape providers toggled on, Hypixel freezes the game a few seconds after world join (reports were 10-20 seconds - for me it's a complete hang, equivalent to a crash)

To Reproduce
Steps to reproduce the behavior:

1. Go to capes settings and enable one or all of the affected cape providers
2. Join Hypixel and wait a few seconds while chunks load
3. Get a huge hang/slutter

Expected behavior
No lag.

Context (please complete the following information):

• Minecraft version: 1.19.2
• Capes version: 1.4.5
• Mod list: General optimization mods - the issue was isolated to with Capes.
• Server: Hypixel

Additional context
The problem was discussed in the Fabulously Optimized discord server for a while on a support thread. I could relate this to the early issue in Vanilla, where requests to the Mojang servers to check whether a player is ignored in chat blocked the render thread and caused severe lag spikes - you could dig in this direction for the fix.
The affected cape providers (slow response times?) were Cosmetica, LabyMod, Wynntils, Cloaks+

After some time it was determined that it was caused by pairing Capes with Lithium.

As it turns out it actually is some mod causing it as an incopatibility. Will try to isolate the one too.

It was Lithium. What a crossover.

edit: fully sure about it now - happens with only lithium and capes.

The bug, as it turns out, also causes a slutter upon opening the config menu (loading the player preview?)

Seems to still happen in 1.5, guess its time to fully investigate it

This time I actually tested it properly and it should be fixed in 1.5.1.

And thanks to @HeyZeer0 for instantly identifying the problem and how to fix it.
