2 solution puzzle

It will be hard to play queen vs rook and two pawns for a human, maybe Stock fish can. But the move suggested by engine wins the rook before promotion.

Try yourself to beat the engine with c2. If u can, u can cal it a bug. Hints are not allowed

I tried it against stockfish 8 and its a draw rook always controls the f file so king cannot enter the critical squares
