server crash when the pregen start 1.20.1

[SPglouglou]

I have Chunk+Pregenerator-1.20-4.2.3 on forge 47.2.17. And when I start generating a piece, the server instantly crashes with this error: java.lang.NullPointerException: Cannot invoke "java.util.Optional.orElse(Object)" because the return value of "it.unimi.dsi.fastutil.longs.Long2ObjectMap.get(long)" is null

here is the crash log: https://pastebin.com/7r1xNYNf

That is lithiums poi optimizations crashing due to a memory leak I have fixed.

Simply disable the poi optimization or disable lithium until the pregeneration is done.

thanks disable lithium solved this issue but now for all chunk generated it throw this error and stop the generation.
