It's a bug report by one of the utopian community manager, which details how the app crashes when he tries to play a demo. It's not the same, but definitely not totally different.
No dude, that's not how testing works. Bug should be able to being reproduced on any device that is supported by the software version. If the error is relevant only for your device (which BTW you didn't specify), then it's not really a bug with the code, more a bug with your hardware, so to speak.
But, other model I tried loading failed to do so. I suspect these issues are already known to the PO, as can be seen with this bug report:

The issue reported in the link you provided is totally different, even how to reproduce it is diferent, the user there is talking about demo.

Please make use of a mobile phone not pc, using the same operating system, and see how it works.
