What's Wrong?

Not sure if this only happens in the "yes" answer, to give permission to run or do something, but after pressing the option, the confirmation prompt stays open, and it seems time keeps passing, and I need to press one more times to really close the prompt and see it doing something. And afterwards, shows the answers multiple times (the times I needed to press).

⏺ That sounds like a known UI glitch — the prompt captures the keypress but doesn't dismiss until a second input event arrives, and the duplicate entries are the repeated keypresses being rendered. It's a terminal input handling race condition in the prompt library.
