The app crashes when `TreeViewFragment` tries to access its context while it is detached.

[euptron]

Problem Description

The app encounters an IllegalStateException in the TreeViewFragment class when attempting to access the context of a fragment that is not currently attached. This issue arises because the TreeViewFragment tries to use its context while it's detached, leading to a crash when handling asynchronous tasks.

Steps to Reproduce the Behavior

1. Open the app and navigate to a section where TreeViewFragment is used.
2. Trigger an asynchronous task that requires accessing the fragment's context (e.g., populate file tree data).
3. Observe the crash, which occurs when the fragment's context is accessed while it is detached.

Expected Behavior

• The app should handle asynchronous tasks in TreeViewFragment without crashing. The fragment should be properly checked for attachment before accessing its context to ensure smooth data operations.
