Possible fixes

Seems the error happens during file opening failure, when trying to alert the exception, which is incorrect type:

chatwoot-mobile-app/src/screens/chat-screen/components/message-components/FileCell.tsx

Line 33 in 3ff0483

FileViewer.open(localFilePath).catch(e => Alert.alert(e));

This crash (Value for title cannot be cast from ReadableNativeMap to String) was fixed in #1140 (v4.9.1) by passing a string title to every alert dialog. Closing.
Please reopen with a fresh logcat if a PDF still crashes on 4.9.1+.
