Game crash in champ select

Been meaning to post this for a while

This issue has been affecting me for quite some time. With my current schedule, I barely have time for just one match per night with bae. Usually we get into a match. However, there are times where this issue causes us to be unable to play

Summary of the issue: Everything will start out normally. We will begin to ban champion. As the ban phase ends however, there is a chance that the process will randomly stop responding and the game will require a force close.

I had typed a message and sent it the moment ban phase ended. This may be a possible cause, but I'm not sure

Please help me
