[Bug]: Crash on joining world

[tmvkrpxl0]

Minecraft Version

1.20.1

What happened?

When I join the world, it sometimes crashes immediately with ConcurrentModificationException: null. I think it's because of this line:

elytraslot/forge/src/main/java/com/illusivesoulworks/elytraslot/platform/ForgePlatform.java

Line 32 in 1f1eb29

private static final Map<String, Boolean> CACHE = new HashMap<>();

Forge loads mods in parallel so I think you should use ConcurrentHashMap

How do you trigger this bug?

1. Join world
2. ???
3. Crash
