the menus in my game WILL NOT OPEN

I haven’t had a moment to try the window thing yet because it hasn’t happened again as of yet. Sometimes it happens sooner sometimes it happens later but when it does happen again I will do it. As for grim. I loaded a tester profile and it works fine. He was reaping and everything went well. I didn’t take anything mods out. I’m confused why it worked in that save but won’t work in this save. I don’t want to lose my progress in this save any suggestions on how this can get fixed.
