I'd apologize for the inconvenience and quickly assess the situation. I'd offer to restart the demonstration or provide a alternative method to showcase the app's features. I'd explain the rare occurrence and assure the audience that it's not a common issue. I'd invite the audience to ask questions and engage in a discussion about the app's capabilities. I'd provide a demo on a backup device, if available, or offer a hands-on experience with the app. I'd emphasize the app's core value proposition and highlight its benefits. I'd also offer to send a follow-up email or provide additional information after the presentation. By staying calm and composed.

If the AR app crashes during a critical demo, I'd remain calm and acknowledge the issue immediately. I'd reassure the audience that technical glitches happen and offer to restart or switch to a backup plan. To keep engagement high, I'd explain the core features and value of the app while resolving the issue. If possible, I'd demonstrate the app on another device or provide visuals that represent the app's functionality. I’d encourage questions and make the session interactive to maintain interest. Afterward, I’d follow up with additional information or a private demo to ensure everyone experiences the app firsthand.

If my AR app crashes during a critical demo, I first acknowledge the issue calmly and assure the audience that this can happen even with cutting-edge technology. I then shift focus to discussing the app’s core features and benefits using pre-prepared visuals or slides as a backup. Engaging the audience with relatable industry anecdotes or humor helps keep the mood positive. I might even use the opportunity to highlight how overcoming these challenges is part of the development process, turning a tech issue into a learning moment and maintaining credibility.

During unexpected tech issues, I quickly acknowledge the problem to maintain transparency, pivot to backup content to keep the audience engaged, and use humor to lighten the mood. This approach helps maintain composure and keeps the presentation on track.
