The duplex-dilemma tile-puzzle

The tile-puzzles were one of the first interactive puzzles in the clickmazes collection and over the years I've continued to explore different tile-sets. In 2019 I stumbled on two sets of eleven tiles that are all but identical but have quite distinct solutions. The two tile-sets differ by one tile only and that one tile is the mirror image of itself (see illustration below).

A solver program later suggested that the two solutions are both unique*. So can you find both solutions? Click below to try. (for applet instructions please see the tile-puzzle home page).

(*) I remain open-minded that the solver program could be proven wrong!
