There is the problem right there, NPE at that packaged name, That file name, that method (filename.java: lineNumber)

Go to the specified line and see what is happening there, set a Breakpoint and see wtf is "null" in value when used. Then you have solved most of it already.

If you guys dont get it.. then well ya.. try harder...

thank your

i found the error but i am completely blank on how to fix it so for now i removed the code, for now... (it is not need for my mod to run any way)

the error is that i am with 99% change using a wrong way too detect when/if a server is running

        if(!initializedserver) {
            for (TickType ticktype : type) {
                if (ticktype == TickType.SERVER){
                    if (FMLServerHandler.instance().getServer().isDedicatedServer()) { <------- ERROR LINE HERE
                        if(ModConfigCore.ConfigLoadFail != false || ModConfigCore.ConfigLoadFailArmor != false){
                            initializedserver = true;
                            
                            if(ModConfigCore.ConfigLoadFail == true || ModConfigCore.ConfigLoadFailArmor == true){
                                FMLServerHandler.instance().getServer().logWarning(Strings.CONFIG_DIFFICULTY_INGAME_CHAT);
                            }
                        }
                    }
                }
            }
        }

Wouldnt getServer() return null when used upon client side?

That would explain the error at least in theory.

dam i am sooo stupid thanks man it works now

how the code looks now

        if(!initializedserver) {
            for (TickType ticktype : type) {
                if (ticktype == TickType.SERVER){
                    if (FMLServerHandler.instance().getServer() != null) { <---- changed .isDedicatedServer() to != null
                        if(ModConfigCore.ConfigLoadFail != false || ModConfigCore.ConfigLoadFailArmor != false){
                            initializedserver = true;
                            
                            if(ModConfigCore.ConfigLoadFail == true || ModConfigCore.ConfigLoadFailArmor == true){
                                FMLServerHandler.instance().getServer().logWarning(Strings.CONFIG_DIFFICULTY_INGAME_CHAT);
                            }
                        }
                    }
                }
            }
        }

EDIT---

by the way when i tried to use my mod in normal minecraft i got a wired crash report

and i can see that it is something with the setUnlocalizedName

jarJar not working

Try replacing implementation with minecraftLibrary. Dependencies in the minecraftLibrary configuration are added to your compile and runtime classpaths in ForgeGradle 6.

Failed loading villager cartographer registered at cartographer - frozen tick

Allocated 10 Gb of ram. Could try again with more but I read using too much can slow things down as well. Going to try another big modpack and see if i can replicate the problem. It seems like this cartographer problem is kind of popular and doesn't have a solid solution yet, but i suspect its some generation mod since it's a crash that happens when specific chunks are being loaded. so i'll still try to lookout for what mod it could be as i add. i'll report back after testing as you suggested for a bit

I have no idea - is enough RAM allocated?
Do other pre-configured modpacks work? Maybe use such a modpack as working base and add new mods one by one
