Not sure if you're still updating this version, but I just discovered a soft lock with the first boss you meet that explodes. After using loving parasite on it, I left it on 1 HP where it immediately explodes after ending my turn, and I got parasite back, but it went into my discard pile instantly. Then, I think the game got confused about what the state was, and never drew my next set of cards. It was quite unusual, as this was my first softlock after so many runs.
