Literally Impossible Solo Chess Puzzle

Solo chess gave me an impossible puzzle. It’s possible I am dumb, but I still think this is glitched.

Pawn a3, Kb1, Qb2, and Rg3. That’s it. The king must be the last piece to capture, and each piece can only capture a max of two times.

okay so the solution is as follows.
1. Rxa3
2. Kxb2
3. Kxa3
The king has captured twice and only one piece remains on the board.
