Emacs periodically saves all files that you are visiting; this is called auto-saving . Auto-saving prevents you from losing more than a limited amount of work if the system crashes. By default, auto-saves happen every 300 keystrokes, or after around 30 seconds of idle time.

Suggest you try making your auto-save-interval variable much larger and see if that helps

Also suggest making smaller .org files when practical

Same here with 3 different Emacs versions.

I did not have a crash here, though.

In a discussion on Org/Emacs scalability issues, I got a hint[1] to use
gcmh.el which indicates garbage collecting activity. My
freeze-moments are almost entirely related to garbage collecting.

You might want to try that.

I've got no solution or workaround so far.
