[BUG] Runtime error when opening NSFW tweets

[geominorai]

Describe the bug

Opening a NSFW tweet (either by URL or one saved in the app prior to Twitter blocking access) results in a runtime error. Understandably, the main issue for being unable to access NSFW tweets in general is currently unresolved in #658, but a more descriptive error as a placeholder like an access forbidden error would be more informative for the user in the meantime.
