The project manager should schedule a session with the team to discuss the issues and work with them to define a plan to manage the sprints going forward. This will help to address the team's concerns, resolve the conflicts, and improve the team's morale and performance. The project manager should also communicate with the product owner and other stakeholders to align the expectations and priorities for the project and the support items. The project manager should also use agile principles and practices to adapt to the changing requirements and deliver value to the customer. Requesting a replacement, scheduling a session with the product owner, or asking HR to send the team members to a workshop are not the best ways to proceed, as they may not solve the root cause of the problem, damage the team's trust and cohesion, or delay the project delivery.
