How do I learn bike handling skills as an adult?

I learned to ride a bike as a child but never learned how to actually manage corners. I can dismount and walk around the corner or attempt the corner and wipe out. I'm no longer willing to wipe out because I'm no longer a child and recovering from a previous bike wipe-out in which I crushed several bones in my left foot(✨). I know that the proper way to learn basic bike handling is "just ride around, you'll pick it up" and I don't know if any person or service even exists to explicitly teach this. I have no idea how or where to look.

✨ Not from turning a corner. A rabbit jumped directly under my front wheel.
