Are you sure you're looking at whatever file was saved? You may be
looking at a different file.
If you really did lose your content, then I think the usual general
advice applies: don't kill a process that contains unsaved data, because
you might lose it.

Hit the escape key. R checks for that at regular times, and aborts
calculations. It is possible to run things that don't do the checks, so
it isn't guaranteed to work.

Recover it from a backup. Use a version control system so that you have
backups routinely on request (and remember to request it), or a backup
system like Time Machine on MacOS so you have hourly backups automatically.

No, but if you can make it happen reproducibly when it shouldn't, we'll
try to fix it.
