Just updated everything for 1.19; forge, my mods, resource packs, shaders, optifine, drivers, java, etc. Everything is fully up to date. Before I updated everything worked but now it crashes as soon as I git play on the launch screen. Error: java.lang.NoClassDefFoundError: net/minecraftforge/client/model/data/IModelData Exit Code: -1 ---- Minecraft Crash Report ---- // Don't do that.

Heck yea, that resolved the issue! Thanks so much! 10/10

I am having the same issue. When you went to the linked site, which of the OpenJDK options did you choose? 8 (LTS), 11 (LTS, or 16 (Latest)?

Howdy all I have been trying to download and install forge off and on for about a month now. I have the latest java and the file needed downloaded but the forge download will not open. I have tried several methods to get it to work, got rid of everything and redownloaded, etc. I had it working perfectly on my old cpu but once i upgraded and got a legit gaming PC it just refuses to work. Any new suggestions or helpful stuff? Thanks in advance.
