freezing while saving

every time I go to save my game it freezes on the save screen. it happens when I save and exit or just save the game. I do have mods, I have cleared my cache, organized through my mods folder, and deleted conflicting mods. I have not checked my cursed forge mods. I have tried saving once every 10 minutes, it allows me to save around 5 times before freezing again. I tried this to save a bit at a time and not overload my game. makes no sense it only allows me to save a couple times before freezing again. getting so tired of restarting every day please help!
