Help if someone know what issue is

Does this happen when you play the mod by itself?

no when its loading into minecraft

I tried separate with every mods and its working but when i am using it in modpack with all this mods i get error so i dont know what to do

Wait so you can run all the mods separately with this mod and they work fine? What modpack are you using?

so you cannot play the mod at all? not even by itself?

yes i can

maybe is then some conflict with some mod

Most likely yes. I would advise doing the following:
Taking out half of your mods
Attempting to load the game
If it loads, the problematic mod is in the group that you removed
If it doesn't load, the problematic mod is in the group you currently have left

Keep splitting each group and testing until you can find the problematic mod and then report back

It looks like someone... deleted the bow model properties? That sounds like a bad idea.

Very bad. Whichever mod is doing that, please let us know, I'd like to hear their reasoning behind that.

i have valhelsia modpack but i added some more mods

crash-2021-05-19_00.24.46-fml.txt
i separate mods that i put in valhelsia and tried to load them with dungeons gear and i get this error, now i tried separate those mods and it works just fine only when those mods are together i get error

I think i found a problem it was The gems project mod , now its working again when i removed it

Let them know about this issue, I can't seem to find the problem in their mod's code
