When I start up my modpack I keep getting this error. I didn't download any duplicated mods and I don't know how to fix it. Here is the crash report: crash-2021-07-06_10.27.04-fml.txt
I have downloaded all my mods for my own custom modpack but whenever I start up the game it always crashes.
Note: I downloaded all mods from the CurseForge launcher and all mods are up to date.
