Game freezes and/or crashes when trying to go to "Resource Packs" menu

Help. Please. On my Nintendo Switch, when I go to Resource Packs, the game crashes. I don't know how, or I don't know why, but this is annoying. I was trying to activate an Add-On, until the game froze. When I close the software, it says "The software closed because an error occurred." Please, PLEASE, fix this in 1.21. (Or any other 1.20.80 or 90) Thank you. (And do this on other systems if it happens there too.)
