This might happen if you have not enough memory. The game needs 2GB+ of memory to run in the web browser. Unfortunately it is a limitation that we have met, making a browser version of the game. On other platforms the game require much less memory. You may try to close other applications and browser tabs, to free memory which will probably make the shop window open without crashes.
