Unable to Close Panel After Adding Question with Empty Content in Channel

[GarvitSinghal47]

Issue Description

When attempting to add a question with empty content (no question inside the ID) in the "New Quiz" section under Coach > Class > Plan > Quizzes, while signed in as an admin or coach on the develop branch, the expected behavior is for the panel to close upon clicking the cross. However, the panel does not close as expected, and the screen gets stuck on that frame. Subsequently, users have to resort to using the back button to navigate out of this state.

Observed Behavior

The panel does not close upon clicking the cross icon when attempting to add a question with empty content, resulting in the screen getting stuck on that frame.

Expected Behavior

The panel should close upon clicking the cross icon, regardless of the content of the question being added, ensuring smooth navigation within the application.

2. Navigate to Coach > Class > Plan > Quizzes.
3. Enter the "New Quiz" section.
4. Attempt to add a question with empty content (no question inside the ID).
