Can you post a log of the errors?

A. You are using the functionality for a bot/cheat. B. 1.16.5 is no longer supported here. We only support 1.18.x and 1.19.x.

1.16.5 is no longer supported here. We only support 1.18.x and 1.19.x.

Split your mods folder and see which has the problematic mod. Do this until you whittle it down to one. Additionally, if it is on a certain mob or with a certain item held/equipped, that might be the problematic mod.

You might want to censor the IP address while you still can. (It's at the bottom of the report. Hopefully no-one else has seen it yet.)

1.9 is no longer supported here. We only support 1.18.x and 1.19.x.

Try doing a binary search with your files.

Mixin only supports Java 18 or lower.

1.16.5 is no longer supported here. We only support 1.18.x and 1.19.x.

1.16.5 is no longer in support and we don't do that kind of thing here. Either make it yourself or ask somewhere else (Fiverr maybe?).

May be a stretch but to me it looks like it may be backdoored. I would recommend running some sort of virus scanner.

1.7.10 is an ancient version from caveman times. No-one has the source for it anymore and will not go through the trouble of fixing things that only affect you. The only thing I can suggest is keeping your drivers downgraded, upgrading your Minecraft Forge to a more modern version (1.18.x or 1.19.x preferably), or switching out your drivers entirely, or maybe uninstall OptiFine if you have it installed because that causes a lot of problems.

1.6.4 is an ancient version from before the dinosaurs and it is therefore not supported here. We only support 1.18.x and 1.19.x.

This doesn't belong on this forum. When it says "Report this Error", it means report it to Mojang, not just anyone who has anything to do with Minecraft whatsoever.

What mods do you have installed? Does this only happen if you launch the pack with Curseforge? If so, it's a Curseforge problem (which is not a Forge problem; they are two different things).

You can join the Forge Discord server and ask there. If they aren't stupid questions we'll answer them for free. (If they ARE stupid questions we won't answer them at all; just because someone doesn't answer you doesn't mean your question is stupid, it might just be that no-one saw it, but someone will likely tell you if it's a stupid question if it is.)

But is this reproducible in vanilla? That's what I'm asking. If so, it's not a Forge problem.

Have you made sure this doesn't happen in vanilla. If it does, it belongs on the vanilla bug tracker (if there isn't already a ticket for it).

I suggest doing a binary search, cutting your pack in half, seeing which one crashes, and repeating until you find the problematic mod.

1.12.2 is no longer supported here. We only support 1.18.x and 1.19.x.

This appears to be truncated. If this is not the full log, please post it via Gist or Pastebin. If it IS the full log, please post the launcher.log (located in run directory). Again, please via Pastebin or Gist.

You are using Fabric. The Forge forums only support Forge. Ask where you'll get support.

Shrink the font! No-one can read that.

Winrar likes to take control of jar files, but you can still open them with java. Additionally, 1.12.2 is out of support and you will need to upgrade to 1.18.x or 1.19.x to receive support.

1.16.5 is no longer supported here. Please upgrade to 1.18.x and 1.19.x to receive support.
