What changes do you do before this issue happened?
Does anyone have the same issue in this team?
Does this issue only happen in Purpose Impact team?
You could check if the SharePoint page shows properly in Teams web client(https://teams.microosft.com).
Besides, log into Microsoft Teams admin center(https://admin.teams.microsoft.com/policies/manage-apps) to inspect if SharePoint related apps are allowed.
