The cprofile.create_stats() might return {}
When self.stats = {}
"if not self.stats:" will be True and exception triggered.

Could you please more verbose describe your proposal? To which exactly file you refer, to which CPython version? In the current main branch method you might refer to looks like this:

cpython/Lib/cProfile.py

Lines 52 to 54 in d05140f

	def create_stats(self):
	self.disable()
	self.snapshot_stats()

It's too difficult to tell what's being asked here. It sounds like buggy behavior, but we need a reproducer and whatnot. @Chungwei5, please open a new issue with the bug template.
