What happened?

Either every hour or every couple of minutes, my game freezes. It first starts to stutter and then freezes until I have to force it to close. It takes longer to start up the game than I actually get to play about 50% of the time.

I've reinstalled and restarted, and I have tried different amounts of allocated RAM: 8GB, 10GB, 16GB, 24GB, and 32GB. None seem to fix the issue. The higher numbers actually seemed to be less stable, so after some web searching, I now stick with 10GB as this has been recommended the most.

I don’t know what to do.

I've checked the open bugs that were listed but none seemed to be like my issue.

While having these stutter problems, do /spark heapsummary and share the log it gives please
There are several known memory leaks, the easiest ones to trigger are hyperboxes without force loading and sophisticated backpacks / chests being used in mob farm setups

As I am playing on a server I do not have access to this command, the admin told me i could use "/sparkc profiler start --alloc --timeout20"" instead which i did but it said my system does not support this.
