Environment
Confluence version 7.x or above
Team Calendar version 6.02x

Solution
Resolution
According to Team Calendars Version History, TC 6.0.2x is compatible with Confluence Server 5.10.7 - 6.14.3. After upgrading Confluence to 7.x, you'll have to update the Team Calendar app to a compatible version (6.0.47+).
Log in to Confluence as a System Administrator
Go to Manage Apps
Locate the Team Calendar app
Upgrade to the latest compatible version by clicking on the "Upgrade" button
