[1.21.9] org.spongepowered.asm.mixin.transformer.throwables.ReEntrantTransformerError: Re-entrance error.

Unable to launch the game on NeoForge: latest.log
No crash report is generated, the game window simply stays open forever until closed manually.

This issue only happens when certain Mixins are present. I stumbled across this with the combination of the two pasted below.
Having both no matter the class content leads to the issue. Only applying one of them works fine.
Also haven't encountered this issue with other Mixins so far.

package com.example.mixin;

import net.minecraft.world.level.chunk.LevelChunk;
import org.spongepowered.asm.mixin.Mixin;

@Mixin(LevelChunk.class)
abstract class LevelChunkMixin {
}

package com.example.mixin;

import net.minecraft.world.level.chunk.storage.SerializableChunkData;
import org.spongepowered.asm.mixin.Mixin;

@Mixin(SerializableChunkData.class)
abstract class SerializableChunkDataMixin {
}

This issue was reproduced using the Architectury Template and copying over the two Mixin classes.

Additional notes:

• The issue does not happen on Fabric in the exact same environment.
• The issue does not happen using the official NeoForge template with the ModDevGradle plugin
