Apologizing before you understand what you did is just trying to end the awkward part faster.

A quick sorry serves the person saying it. It lifts the discomfort, closes the scene, and leaves the other person holding something that has not been addressed, which is why it so often makes things worse rather than better. An apology is only worth anything when it names the specific thing.

Before you apologise next time, sit in the awkwardness long enough to work out what happened from their side. Then say that part out loud: what you did, why it landed the way it did. It takes longer and it is the only version that repairs anything.
