Hi Esteban,
Thanks for pushing it forward! :)
Unfortunately there is still The Typing Crash Bug. But now I found a way how to 100% reproduce it:
1) Open any text editor (Playground)
2) Hold "s" button so it starts typing many "s" in playground. Press for ca. 3-4 seconds.
3) Release "s" button
4) Press left arrow
5) ....
6) crash!
Here is a video of two consecutive crashes:
