This is wrong, the existence or nonexistence of a play does not matter.

Force-Play-Slide Rule
SECTION 4. The intent of the force-play-slide rule is to ensure the safety of all players. This is a safety as well as an interference rule. Whether the defense could have completed the double play has no bearing on the applicability of this rule. This rule pertains to a force-play situation at any base, regardless of the number of outs.
a. On any force play, the runner must slide on the ground before the base and in a direct line between the two bases. It is permissible for the slider’s momentum to carry him through the base in the baseline extended (see diagram).
Exception—A runner need not slide directly into a base as long as the runner slides or runs in a direction away from the fielder to avoid making contact or altering the play of the fielder. Interference shall not be called.
(1) “On the ground” means either a head-first slide or a slide with one leg and buttock on the ground before the base.
(2) “Directly into a base” means the runner’s entire body (feet, legs, trunk and arms) must stay in a straight line between the bases.
b. Contact with a fielder is legal and interference shall not be called if the runner makes a legal slide directly to the base and in the baseline extended (see diagram).
A.R.—If contact occurs on top of the base as a result of a “pop-up” slide, this contact is legal.
c. Actions by a runner are illegal and interference shall be called if:
(1) The runner slides or runs out of the base line in the direction of the fielder and alters the play of a fielder (with or without contact);
(2) The runner uses a rolling or cross-body slide and either makes contact with or alters the play of a fielder;
(3) The runner’s raised leg makes contact higher than the fielder’s knee when in a standing position;
(4) The runner slashes or kicks the fielder with either leg; or
(5) The runner illegally slides toward or contacts the fielder even if the
fielder makes no attempt to throw to complete a play.

Unfortunately, by rule, you have interference here. Whether you should pass on it or not is another matter all together.

Understand for those of who believe that since there was no play there was no interference, you are wrong. Given that

The intent of the force-play-slide rule is to ensure the safety of all players,

requiring that there be a play to enforce the rule would give R1 an opportunity to wreck middle infielders if he were sure that the middle infielder would or could not make a play at first.
