I first noticed it on 1.5.1 StellarMate OS when I updated to KStars 3.4.1 (stable release). but it happens on KStars 3.4.1 on my Mac OS as well. I start up KStars/Ekos, connect simulators/drivers, run auto-focus by manually pressing the AF button in the focus module (Linear/iterative or poly, doesn't matter which), set up 2 o 3 60 second exposures and set the sequence to re-focus every minute in order to save time but this interval doesn't seem to matter.

EDIT: I just tried to run the sequence while skipping the first "manual" auto-focus routine and it crashes KStars every time. Logs attached.
