Minecraft loading screen keeps reloading (using all of fabric 3 modpack for 1.16.5)

[Jqsmine]

Hi so ive just recently installed all of fabric 3 from curse forge to play on & was super excited. I loaded the game and everything was going well but when the *ding* sound went off which normally means you're about to load into the main menu, it showed the main menu for a second before going back to loading and it would repeat this process indefinitely. Im not sure what to do.
