Help me with my minecraft modpack?

I made a minecraft modpack and where I started it I had an error

Error: java.lang.VerifyError: Inconsistent stackmap frames at branch target 47)

Solution: Update the mods

https://files.minecraftforge.net/...forge.net/

Download the Forge 14.23.4.2767 from this page and try it. Recently, I had advised someone here to try and then ran his mod pack. The version jump from 14.23.4. * To 14.23.5. * Seems to have changed some loading handler, or something else and probably not all mods can handle it. An attempt would be worth it at least here too. Otherwise you have to continue research…

It had not worked out

Mhh, too bad. It gets stuck with ExtraUtilities. Vlt throw out times and see if it loads without… Or even update the version of it. The 1.7.3 is from Jan'18 and now they are at https://minecraft.curseforge.com/...ties/files

If there are other newer mods in between, problems can arise as well. So that can have many causes. Ggf is the last 14.23.4. * Of Forge too new for the old ExtraUtilsVersion ect…

Generally, did you put the modpack together on your own? Or is it a finished pack? Vlt is at the DL side of the pack so a version recommendation. Otherwise, if you have put it together yourself, make sure that you get the newer versions of the whole mod's…

I started it without extrautilities but it crashes as soon as I want to generate a map. https://www.reddit.com/...ce510200f2

Description: Exception in server tick loop

I mean either I point out that Minecraft does not get baked the world's creation, because the many mods exercise a lot of load, or a mod still makes problems in the world generation. I can only recommend to update all mods. And then try again. Had this error ever before in the game, and Minecraft had since my computer quite a burden… It was probably time to problems with the server ticks… After a restart, but everything went back… The first generation of the world is of course also hungry for performance…

But I have to admit that I'm not really familiar with Java and programming, and I can't do much with those lines of the log. It may also be that a 2nd World Start attempt works. Unfortunately my general knowledge ends now…

I will first update all mods and then look again. Nevertheless, thanks for your help.

Give all the mods out of your modpack, and give in and out mods and see if minecraft starts!

I've already got it
