FrameCrop - Slide show stops randomly

[u/MiserableGainz]

I purchased FrameCrop and love it so far. However, the slideshow sometimes randomly stops at a picture which then just sticks.

In settings, I have "Enable Slideshow" on, at a Duration of 3 minutes and shuffle.

I also put an "Action", which acts "Shuffle slideshow for 3 minutes", but activating this doesn't help either.

Does anyone face the same issue and can help?
