--- Comment #14 from Patricio Villar <patovm04@gmail.com> ---
UPDATE: I think I finally made some progress to workaround this problem:

I used to have a little devd script that locked my screen when resuming from
sleep. It never did any harm on FreeBSD 11/12 so I didn't think it could be
problematic now, but it turns out it may have been the culprit... After all,
something definitely changed on 13.0.

What I did was modify the moment when this script was executed: instead of
becoming active at resume, it is now triggered when closing the lid (which
means, before suspend).

I don't want to assume this is the ultimate solution or something, especial=
ly
since so many assumptions have been made to this point, but so far it REALLY
seems to have fixed this issue for me.

I've had about 20+ successful and uninterrupted (this is, without shutting =
down
or rebooting in the middle) suspend/resume cycles without any issue. And I'=
ve
really tried to make it difficult to succeed by having multiple programs
running at the same time and stuff like that.

I don't know if some of you too have some kind of custom scripts that get
executed at resume time, but if that's the case, I encourage you to switch =
them
to run while going to sleep instead, or even drop them altogether, and see =
if
it makes a change for you.
