Interaction for menu is wonky on largest breakpoint but works smoothly everwhere else

Hi there! I know animations and interactions are global across all breakpoints, but on the largest breakpoint I have (1440x and up), my menu interaction is wonky. I have my menu triggered by a mouse (on click). It slides (eases) in from the right to left and eases back when closed. On all breakpoints down from 1440x - it comes in nice and smooth and returns in the same manner BUT in the largest breakpoint, which is actually the breakpoint of most desktops, it comes in rushed and returns too fast.

I cannot, for the life of me, figure out why! I’ve done this on other sites before without fail - see no issues. Wuold absolutely love some help!
