Help! MultiMC Can`t Launch 1.20 Version!

I would say switch over to prism launcher (Prism launcher supports multimc instances/detecting them and installing them.) Also seems like it’s an Access Denied error so yea, I’m not quite sure how to fix this. I would say try backing up all your files and deleting the directory and pasting those files back. You can try backup the files and deleting them to see if multimc will reinstall the files. Lastly, this isn’t the right fourm to go on for help. And please, for the love of gosh, USE PRISM LAUNCHER!!! Just search up multi mc situation and you’ll know why.
