The "Component Error" message is appearing because the domain name is not configured for all users in your Salesforce org.
To resolve this issue:
1. The Salesforce administrator should change the domain name for your org. Note that updates to domain names may take up to 24 hours to reflect in Salesforce records.
2. Once the domain name is set, the Salesforce Administrator will receive an email notification. Please request them to deploy the domain name to all Salesforce users by clicking the "Deploy it to all users" button.

4. After the domain name is set and deployed to all users, the "Component Error" message should no longer appear when accessing the TimeTracker configuration screen.
