Minecraft win10 crashes right before I am able to type out a command.

Here is a link to a video of the crash happening: crash. before the recording linked I was able to recreate the crash 3 times. I am building inside the "Hilltop lifestyle" map using the respective raytracing texturepack that comes with the map. I attempt to type in the command "/fill # # # ~ ~ ~", however when the exact state of that command is about to be reached and is only missing one character, regardless of which character, the game crashed before it is able to show "/fill # # # ~ ~ ~". In the previous attempts I have tried to complete the command in a different order, which didn't change anything.
