Hi ! I tried to launch a custom modpack, and everytime I try to launch it, it crashes and give me this error : "The game crashed whilst initializing game Error: java.lang.VerifyError: Bad access to protected data in putfield"

Tbf, I don't understand a single thing about why it's crashing, so I'm asking for a little help ❤️ Thanks in advance if you can help me !

Here is the log :
