Broken Navigation Sidebar Menu on Mobile Breakpoints

Hi all, this is my first post here. I’ve been designing a portfolio site and had everything working on each breakpoint functionally. After 3 or so months though, the sidebar on my tablet and mobile navigation menu broke. The styling is visually fine on the menu before pressing the button to open it, however, once pressed it seems the height of the menu changes so it pushes the content off the screen. Any insights that might help me resolve this issue would be appreciated. Thank you!
