UEFN crashing or freezing when trying to start a session

Summary

Everytime i try to launch a session,it loads, then freezes at 24% (literally everytime i’ve done it). i open task mangager and everything seems fins, but after like 10 mins, its still frozen and my memory and storage & have gone up to 90%+ , i’ve already changed my virtual memory, its at 64gb so i don’t really know what to do, there’s not even much in my project. After like an hour i finally loaded into a session but when i tired to push changed, same thing happened. it causes my whole pc to freeze and run slowly until it crashes. please help.
