Prusa Mini issues with very slow extrusion

Hi there, I've been having a little trouble printing models with my MINI+, when there is very low extrusion between retractions. The Extruder grinds the filament through, and then the filament in the hotend burns until it gets stuck as well.

It usually only happens when I print extremely fine things like DnD (2") miniatures at .05mm layer height.
For now I've switched to .15mm layer height and have not had the issues since, but I wonder if there's something that could be done, except changing the Extruder/Hotend?
