I also ran into this issue while making a Raspberry Pi kiosk type application.

I found that it always seemed to stop within 20-30 minutes but the stop time
wasn't consistent.

A made a workaround where I monitor the slide index and if it doesn't change
within a few seconds of when it's supposed to, I manually advance the slide.
This works very reliably and the slideshow will continue for over an hour after
before freezing again and I thought that seemed suspiciously like a pattern.

I started logging the stop times and found that after the first stop, which is
seemingly random, it always stops after 71 minutes 34-35 seconds. When
converted to seconds it's 4294 seconds. In microseconds that's 4294000000 which
is just about the max number you can get from a 32 bit unsigned integer which
is 4294967296.

It seems that this bug is definitely a result of running on a 32 bit system and
the slideshow timer seems to be using a clock that runs independent of
libreoffice/impress because it stops at a random time the first time after
starting the slideshow.

I'm also using Raspian Buster, libreoffice 6.1.5.2
