MysticDaedra

I cannot leave the menu once I've opened it by hitting Esc while in-game. Neither tab (the "assigned" hotkey) nor Esc which has always worked in the past will allow me to leave the screen. Sometimes Saving/quicksaving works, but obviously that's not a solution to the problem. Any ideas what could be causing this? It is entirely possible it is a mod, but I can't figure out for the life of me what could be conflicting here. For reference, I am using a 99% pure installation of the TUCOGUIDE: https://www.nexusmods.com/skyrimspecialedition/mods/10694?tab=description
