INF-1594

Description

I resolved an issue that occurred when navigating to the learner profile of a non-existent user. Previously, the user's page would display a perpetual "loading" spinner, but it now correctly displays the content of the "Not Found" page.

Screenshots/sandbox (optional):

Include a link to the sandbox for design changes or screenshot for before and after. Remove this section if it's not applicable.
