I've been trying to load up some modded minecraft for a few days, but no matter what I do that game just crashes. When I try without Forge, 1.12.2 works just fine.

Send us a screenshot of your mods folder, it seems like forge believes you have extracted the jars into the mods folder. A typical mods folder should look something like this:
Also, you should send us this file: C:\Users\tiffany\AppData\Roaming\.minecraft\crash-reports\fml-crash-2018-09-16_12.30.42.txt
A better way to share logs is to paste them into pastebin and share the link
Read carefully what the crash report says. (9 first lines)

Thanks for the help in advance!
Send us a screenshot of your mods folder, it seems like forge believes you have extracted the jars into the mods folder. A typical mods folder should look something like this:
Also, you should send us this file: C:\Users\tiffany\AppData\Roaming\.minecraft\crash-reports\fml-crash-2018-09-16_12.30.42.txt
A better way to share logs is to paste them into pastebin and share the link
Here's what has been requested:
And here's the Pastebin:

Read carefully what the crash report says. (9 first lines)
Strange, I put the jar files straight from the download into it without extracting.
In your screenshot, you have installed WorldEdit for Minecraft 1.11 and it's a folder.
Remove this folder.
Download WorlEdit for 1.12 here: https://minecraft.curseforge.com/projects/worldedit/files
