this is the error i get when i try to load Minecraft I'm using the latest forge on Minecraft 1.20.1, i looked everywhere on the post to see if i missed something and also tried the few download links i came across but that didn't work either, the furthest i got is with multipiston-1.20-1.2.31-ALPHA-sources.jar wasn't a valid mod, so i deleted it and it went back to crashing my game, lastly i tried the dependencies that were provided on the website but that also didn't work both screenshots are provided of my errors.

You would need to download the multipiston-1.20-1.2.31-ALPHA.jar file, not the one with -sources or with -javadoc in the file name
If that version is not working either, you would need to provide the logs

Wrong file, yes
