Why rook is considered better than the queen?

In this game I promoted my free pawn to become queen. The engine for game analysis suggests it would be better if I promoted it into a rook.
How is the rook better choice than the queen?

After White promotes to a Q in the position shown, Black has 13 legal moves. Not even close to a stalemate.

To the OP: the engine does weird things like that sometimes. There are times when promoting to a R instead of a Q does avoid stalemate, but not here. In this case, just ignore the engine.

stockfish evaluating games is like me talking to a woman, don’t worry about it

yeah I would ignore the engine. I figured it did weird stuff but this is ridiculous... Never seen something this obvious be just a thumbs up before.

As you can see, the engine says it is better to promote to a queen. Perhaps the depth of the analysis wasn't big enough in your evaluation.
