Bug description

When the conversation is opened in a landscape mode, switching to portrait will crash the app. No .IPS file is generated during this crash :/

The bug was already present in december 2025. As far as I remember this bug already happened before and was fixed some years ago.

Steps to reproduce

• Open Signal
• Open a conversation in landscape mode
• Switch your phone to portrait

Actual result: The app crash

Expected result: The conversation still opened in portrait mode.
