The Game Won't Open With This Mod Installed!#799

I tried playing the 1.21.7 version and it refuses to work at all!

I download and add the mod into the Forge Installation's "mod" folder, like I do with every other mod. when I start the game, it just crashes and shuts down. I can't even get to the main menu. I just get kicked to the launcher and an error message saying the following:

"An unexpected issue has occurred and the game has crashed. We're sorry for the inconvenience.
Crash dump sent!
Error Code:1"

What gives?? Why does this keep happening!?

    I have the same issue.

    Using Minecraft 1.21.7 and tried all available Forge Versions for this minecraft version. It is always just crashing with exit code 1.

    Here is my log:
