Here are the mods work work with Architectury I think

Are you sure the main problem is with my mod? The crash log doesn't point to it, and the screenshot indicates that you're just missing the Architectury API

Hey, I'm not good at coding but I've learned about Java a little bit, you should use the ConcurrentHashMap, instead of Hashmap in Java, switching to ConcurrentHashMap is easy. I keep getting concurrentmodificationexception crashin the modpack.

This is your code, hope you can change all the HashMap to ConcurrentHashMap:
package me.adda.enhanced_falling_trees.api;

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Optional;
import java.util.function.Supplier;
import net.minecraft.class_2680;
import net.minecraft.class_2960;

public class TreeRegistry {
private static final Map REGISTRIES = new HashMap();

public static Supplier register(class_2960 resourceLocation, Supplier treeTypeSupplier) {
REGISTRIES.put(resourceLocation, (TreeType)treeTypeSupplier.get());
return treeTypeSupplier;
}

public static Optional getTreeType(class_2680 blockState) {
return REGISTRIES.values().stream().filter((treeType) -> {
return treeType.enabled() && treeType.mineableBlock(blockState);
}).findFirst();
}

public static Optional getTreeType(class_2960 resourceLocation) {
return Optional.ofNullable((TreeType)REGISTRIES.get(resourceLocation));
}

public static class_2960 getTreeTypeLocation(TreeType treeType) {
Iterator var1 = REGISTRIES.entrySet().iterator();

  Map.Entry entry;
  do {
     if (!var1.hasNext()) {
        return null;
     }

     entry = (Map.Entry)var1.next();
  } while(entry.getValue() != treeType);

  return (class_2960)entry.getKey();

}
}

Ah, well, in general this has a place to be, so yes, I'll review it in more detail.

Sorry for the long delay :D, I fixed it in a new commit in the dev branch, I’ll send it for release soon, after the rest of the fixes

That's great to hear, but any info on the falling trees damage player?

[addavriance]

To be honest, I had already considered this before, but not much came of it, so I put it off until new releases. That's why I'm just about to work on it now, along with the porting to 1.20.5 - 1.21. I develop each mod quite intermittently to avoid burnout, so I switch between languages or projects.

Some devs stop supporting low popular versions, I think you should also do that, maintaining many versions is really hard, your FallingTrees mod just missing that feature I believe
