The application crash when sending a message

[Brinfer]

Every time I try to send a text message, the app freezes.

After a while, I get a pop-up telling me that the app is not responding and asking me if I want to close it.
If I select “Wait,” the text message is sent, but if I don't, it isn't.

However, if I try to send a text message to myself, it works fine.

If i answer to a message, using the "quick action", directly from the notification, it works as expected.

I have a Xiaomi A3 running Android 11 with Android One.
The application has the version 8.1.2

I see the same problem when I try to unarchive a conversation.
I don't know if this is related, but if necessary, I can open another issue.
