After the new release of 1.13, I can't use any Forge versions without Minecraft crashing when I try to play. I tried 1.7.10, 1.10.2, and 1.8, but none of them work. I've tried redownloading all of the Forges, I've tried only having one downloaded at a time, but everything has the exact same result.

Please post logs as described in the EAQ and my signature.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

1.7.10 isn't supported on these forums anymore.

Can I get the log for the most recent version you have? and Please use Pastebin or Gist, both are linked in my signature.

I turned off all of my 1.7.10 mods and activated my 1.10.2 ones, but it still crashes when I click "play."

If you mean trying to use 1.13 Forge, no. If you're talking about Minecraft Forge after the update, yes.

No, I mean there is no version of Forge for 1.13 yet, so if you're trying to use an older version of Forge with the new Minecraft client, that's why it isn't working.
