If the character is using any homebrew (particularly any that add spells like an item with charges), remove then and see if that fixes it. This problem is most commonly caused by homebrew that isn't formatted right resulting in it trying to add a spell over level 9.
I receive this error whenever I attempt to access my spells page on the character sheet:
TypeError: Cannot read property 'push' of undefined at https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:1:53603 at Array.forEach (<anonymous>) at https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:1:53349 at https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:1:307744 at https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:1:307171 at https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:1:307874 at Object.getLevelSpells (https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:1:307171) at Function.c [as mapToProps] (https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:50:310065) at r (https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:12:167687) at Function.r.mapToProps (https://www.dndbeyond.com/Content/1-0-305-0/React/CharacterTools/dist/characterSheet.bundle.min.js:12:167806)
