Originally I made a “SysMessage” Vertical Box variable. When I noticed the Issue after restarting I renamed the variable to something else. As the error persisted after a restart I delete the variable (vertical box) from the widgetBP, and the references within gamemode (so blueprint wise the variables and all the references to it were erased). I believe I then restarted again, recreated a vertical box variable (the one that is currently present), and also recreated the references within Gamemode.
I also included all the backups and autosaves of the widget and gamemode blueprint, that contains the variable at it’s various bug states.
