Im having this problem on a world I've been playing for about 5 days, I have tried deleting serverconfig files and that got it to work once, but now deleting them doesn't change anything it will still crash. Im using 1.16.5 with the better mc modpack off of curseforge. When it crashes it gives me the exit code -805306369. I have also tried to allocate more ram which didn't do anything
