I’d advocate for a quick meeting with key stakeholders to discuss options: delaying the release to fix the defect or implementing a temporary workaround if the release deadline is non-negotiable.

Drawing from a past experience, I discovered a similar issue hours before a major update. We decided to delay the release by a day to ensure the issue was resolved and thoroughly tested, which ultimately preserved user trust and avoided costly post-release patches. The key is to be transparent about the risks and collaborate closely with the team to make an informed decision that aligns with the company’s quality standards and business goals.”
