> Thank you for the issue, and apologies for the delay. I can replicate this, but I need to dig into why exactly it's happening. It's possible this is related to the simulated slots feature that we use for components like ion-input and ion-textarea, since the bug doesn't replicate with non-simulated slots like the ones on ion-button.

Start by running the linked StackBlitz reproduction and typing into the ion-input to confirm the crash. Investigate the ion-input simulated-slots behavior when a start or end slot is dynamically removed, and consider the issue done when adding or removing those slots no longer crashes.
