My Forge Version Minecraft won't open!

Posted July 27, 20169 yr

Every time I try to open Minecraft using Forge 1.10.2 it loads, and then opens the Minecraft Launcher with the game output opened, and a very large message saying; 2016-07-26 20:18:36,673 WARN Unable to instantiate org.fusesource.jansi.WindowsAnsiOutputStream

I have only been able to play mods once, and all the other times it has showed this message. I have had Forge for at least two weeks and really want to play mods. Does anyonr else have this problem or know how to fix it? Is it my fault or is it Forge's fault? Please tell me if I can fix it or what's wrong.

NEI couldn't find CodeChickenCore. Make sure you have it installed.

In future, please post the full FML log (logs/fml-client-latest.log in your game directory) rather than a snippet of the console output.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Error Code -1073741819 On new PC no matter the mod no mater the version, even normal java minecraft gives the same erro

2 Weeks ago i got a new laptop and installed on it curseforge and normal minecraft and java, and wanted initialy to test how some modpacks would run to then start a new world to play when i had time.
Fresh windows 11 install, i wouldn't think anything could happen but bam error -1073741819, and i can't find any way to remedy this. I reinstalled java, updated drivers, reinstalled minecraft, launchers, even prism launcher, tried eclipse temurium instead of normal java... nothing seems to work

Forge 1.20.1 OpenAL 40963 and 40961 in DynamicSoundFilters

I copied the mod from Fabric to Forge, but errors 40963 and 40961 appear, I still don’t know the reason, I tried it in a single world, it doesn’t reproduce, the reason for the error is unknown, sometimes it exists and sometimes it doesn’t. andre111/dynamicsoundfilters: GitHub repository
The ported code to Forge is no different from the original, so you can use the source code for testing. The same error occurred on the Fabric build, mods that were on both builds:
Sodium
Create
I only know that the error occurs along the following path: MixinSoundSystem call onPlay -> FilterManager call updateSoundInstance
