Telegram crashes consistently on iOS after logging into this account.
The account itself works normally in Telegram Web. In the iOS app, Settings and Contacts can be opened normally, and individual chats can be accessed through Contacts or Search. However, opening the main Chats list causes the app to crash.
A chat opened through Contacts can also be used to type a normal text message, but pressing Send causes the app to crash. This happens with plain text and in different chats, so the issue does not appear to be related to a specific chat, emoji, sticker, GIF, or media file.
The issue persists after updating iOS and completely reinstalling Telegram.
The crash log reports SIGABRT and includes the following stack: DCTMultiAnimationRenderer-FirstFrame → rlottie::Animation::renderSync → LOTPolystarItem::updatePath → VPath::VPathData::addPolystar → __cxa_throw → abort
A second crash log reproduced the same stack.
The app is currently practically unusable on iOS, while the same account works normally through Telegram Web.
A full crash log and screen recording are available and can be provided to the Telegram QA team if needed.
Steps to reproduce
Launch Telegram normally by tapping the Telegram app icon.
The app crashes immediately.
Long-press the Telegram icon and select Change Icon.
Telegram opens through this menu instead of crashing.
Open Settings. It opens normally.
Open Contacts. It also opens normally.
Tap Chats. Telegram crashes immediately.
Alternatively, open a chat by going to Contacts, selecting a contact, and opening their chat.
Type a normal text message.
Press Send. Telegram crashes immediately.
Repeat with different chats. The crash remains reproducible.
Use the same account in Telegram Web. The account works normally there.
Reinstall Telegram and update iOS. The crash persists.
Current result
Telegram crashes consistently on iOS when opening the main Chats list and when pressing Send for a normal text message in chats opened through Contacts.
The crash is reproducible every time and the crash logs contain the same rlottie/LOTPolystarItem stack ending in SIGABRT.
Expected result
Telegram should open the main Chats list without crashing and should allow normal text messages to be sent without crashing.
As explained you probably have a chat with a sticker / emoji that causes the crash. this is already resolved in Telegram Desktop so you can look for the chat that causes the problem and remove the sticker / emoji from there.
