Bug description

After searching for any word which we'll call keyword and pressing on a message which contained keyword which is from a while ago, the app will hang for a while and then crash, OR the app will go to a black screen and if I exit the app and re-enter, it'll crash.

It seems to depend on how many messages have been sent since then. Searching for keyword and selecting on an appearance of it which is a little sooner to the time searching will make the app hang (like normal?) but eventually load the chat at that date.

Steps to reproduce

search for any word (in this example keyword)
look for an appearance of the word from a while ago in an active chat, given that there have been many messages sent since then (for instance, I'm clicking on a message sent on June 30 in my example)

Actual result:

The app will hang for a while (around 4 minutes average out of 3 attempts) and then crash

Expected result:

Signal should load the message. Signal hanging isn't a big issue although of course the faster the better but at this moment in time old messages are just unavailable due to the app crashing
