Fortnite Log goes up to 23GB in 30 mins and crashes Fortnite

Summary

While waiting to start a session, Fortnite log is exploding up to 22.9GB from 10MB and then crashes. I can’t open the log file so I have no idea what is causing it. I can offer the project files up (which are checked in) if that helps…
