BackSlot incompatibility

Describe the bug No idea which side will have to fix this, but loading the mod together with BackSlot and using the latter's features results in the world crashing thanks to CheckedThreadLocalRandom and a call of Random.nextFloat().

The relevant code of BackSlot doesn't seem to be doing anything special: https://github.com/Globox1997/BackSlot/blob/1.19/src/main/java/net/backslot/network/SwitchPacket.java?ts=4#L168

Could thread locks (or whatever they're called in Java) be added for random instead of throwing exceptions when it's accessed from the "wrong" thread? Might be slow of course.

To Reproduce

1. Load MC with C2ME, BackSlot, (Quilted)Fabric API, Cloth Config
2. Grab some sword and press BackSlot's hotkey (G by default) a bunch of times to put the sword on and from your back.
3. The world crashes. Takes around 3 presses for me.

Expected behavior No crashes, duh.

Using world random on another thread is absolutely wrong and causes weird crashes in vanilla: java.lang.IllegalStateException: Accessing LegacyRandomSource from multiple threads. This should be fixed on their side.

Resolved now. Thanks, @Mephodio! I tried to resolve this myself at first, but that one maven repo going down was a problem. Reached out to its owners weeks ago, but nothing got fixed after promises.
