Does this still happen when you’ve freshly booted the system and aren’t running anything else?
If it doesn’t happen under those circumstances then this is a known issue. The issue is related to the count of processes running on the system (regardless of whether the total load is high), there’s a fix in progress.
I also have this phenomenon frequently only when editing a specific place.
It freezes at a high rate, especially when live scripting indicates that the connection is unstable.
