Game crashes when certain text is sent to chat

Hello. Today, I actived the narrator, using CTRL+B. I tried having it read different messages, and went on spamming the chat. A full-length Message containing slashes, beginning with "." worked just fine. Other spamming messages worked just fine as well. The problem started trying to type in "sing". Now, sending "sing" worked just fine. "singsing" too. What didn't work, was to press Enter, sending:

"singsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsing"

to the chat. When pressing Enter, I got an error message, saying that the program had crashed. I could either close it, or troubleshoot it. I closed the error window, and so the game was closed as well. I tried again, and the same happened. I tried fewer "sings", and it showed to be a certain amount that crashed it. There had to be many. I dont' know the exact number. As said, I spammed the chat with several other full-length messages. This worked just fine.

I now disabled the narrator, and tried sending the above "singsingsing"+ message again. Everything worked as it should. No crash. I then reenabled the narrator. I sent the same message again, but with no crash. Note that there were several crashes. I did not change the narrator settings between these.

Please understand that I have already searched for similar reports, but did not find any that fits this. Thank you for your time. I'd always be happy suggesting new features.
