The user cannot view the designated tasks in their inbox. Whenever the user attempts to refresh the inbox by clicking the refresh button, they encounter a 500 error message.

Error 500 - GET /lc-api/projects/v3/my-tasks-inbox/tasks
The server encountered an error processing the request. Try again later.

The issue has been escalated to the Engineering team and the issue has been fixed with the latest release.

The workaround is to reset the customer filters on the UI and leave the "Customer" field empty or to select a value from the dropdown menu. 

There is a UI bug which allows the "Customer" field to be manually filled by the user, and in this user case it is filled with a backslash "\". This value causes the error returned by the server as it is a special character. Once entered the value seem to also be persisted by the UI.
