Here is a helpful guide covering how to update Telegram to squash bugs, and an explanation of what those update notes actually mean.
Fix #5: Delete a Specific Malformed Message (Advanced)
If Telegram opens for 2 seconds before crushing, you have time to act. The bug might be a single message (often a large poll, a video with broken metadata, or a sticker).
- Quickly navigate to a different chat before the crush happens. Use the "Saved Messages" chat (usually the first in the list).
- If that works, the crush is in your last active chat. On another device (Telegram Web or a second phone), delete the most recent message in that problematic chat. Sync will remove the offending message from your crashed phone.
On Desktop (Windows/macOS/Linux):
- Download the latest version from telegram.org/desktop.
- Install over the existing version (your chats remain).
- Version 4.16.0 or newer contains the fix.
