Okay so i am summing up everything here. To reignite motivation and drive in your team. First make them understand that this The part of software developer's journey and to become a better engineer you have to go through it. Ask them to set a daily target of solving bugs if there are many, suppose 1 person will solve 50 bugs per day that's you distrubute the load and when the person will achieve the target there will be a sense of happiness in him/her. Make them understand that this is the recognition of a senior developer/engineer means the person who can fix bugs/errors is getting knowledge which others might miss. So take this as an honour, this is the part of Journey you can do it while being sad or can do it with full motivation

Unforeseen bugs are indeed frustrating, yet they present a powerful opportunity to strengthen the team. When my team encounters these issues, I address them openly to ensure everyone feels heard and validated. I focus on breaking down complex problems into smaller, achievable tasks to help us regain a sense of control and progress. Each bug we fix becomes a small victory, which I make sure to celebrate—it’s a morale boost that reinforces our teamwork. I also encourage the team to share ideas and solutions, transforming setbacks into a chance for collaborative growth.

Make it a learning experience. We all want to do well and create amazing bug free software, but I always find I learn more about myself and my skills as a developer when there are problems to solve. Every failure in life is an opportunity to learn and grow.

Start by acknowledging that these bugs are part of the development process, especially when working with complex or legacy systems. Remind the team that encountering bugs is a shared experience for all developers and that overcoming these challenges ultimately strengthens their skills and the product. Encourage the team to approach the bugs incrementally. Break down the issues into manageable tasks, with each small fix contributing to a bigger solution. This helps the team see progress and reduces the sense of being overwhelmed.Celebrate every bug that gets fixed, no matter how minor it seems. This could be as simple as a shout-out in a team chat or a quick mention in a stand-up meeting. Recognizing small victories builds momentum.
