    So I am getting some crashes apparently on my live game from players, I got this from the dev center (game is built for 8.0)

    And then I downloaded this minidump file and it opened in VS and says:

    It worked fine when testing on my Lumia 925, I think this might have been a 1025 that crashed.

    I'm not sure what this is telling me or what I can do... thanks for any help!!

    It's telling you that you're accessing data from incorrect thread.

    For ex., you can only access XAML UI code from UI thread, accessing it from different code will result in exception above.

    Though I am not totally sure if you're hitting this exact problem. A bug report would be nice.

    You mean from unity? Or from the Windows dev center?

    I don't do anything with threads etc... I use unibill for in app purchases, but that's it.

    It can be done from anywhere - from Unity, plugin, some other external code. When you open minidump, do you see the callstack?

    When the minidump opens in VS I just see this:

    I had a player tell me:

    It's after he's setup his vehicle and goes to the second scene in the game to play leaving the garage menu that it crashes.

    There's surely no way it's a memory issue with 2GB RAM on the Lumia 1520.

    I'm not quite sure how to get the typical stack trace like I see on Google Play with Android.

    Do you get an option to "run" the dump? If do you, it should show you the stacktrace of all the threads.

    I attached a picture of what I see, I clicked the "Debug with Mixed" link in this action menu on the right. Is that what you were talking about?

    What happens if you press "Debug with native only"?

    "The minidump is from an ARM-based computer and can only be debugged on an ARM computer."

    Without a stacktrace, it's gonna be really hard to find out what's going on - I'm not sure why Visual Studio won't give you that. However, while being more advanced, it's also possible to use WinDbg to extract stack information from a minidump.

    Yes, you should have them. You'll the exact Unity version with which you released the game, and you'll find them in Editor/Data/PlaybackEngines/wp8support/Players/ARM/master/.

    I've never been able to do anything with this crash dump yet however I had one of the reviewers that had the crashing issue try choosing my "low quality" setting, the main difference being that it disables shadows. He said it worked great then! He was on an HTC One M8 which has the Adreno 330. Is this a known issue? What I did was just put a script on the light to disable shadows if running on WP8 for now, uploading the update to the store now...

    I don't think we have such issue recorded anywhere - I haven't personally heard about it. Could you perhaps PM me a link to the game, so our QA could download and test it on various phones?

    Data caps? WHAT YEAR IS IT?!

    Anyway, it would be nice if you could submit a bug. App being not freely downloadable from the store is an issue, but it could be solved by uploading it again as "beta" and letting only selected email addresses to download the application.

    I have to use ATT cell data plan basically... no internet here in the rural area... I know, crazy :p

    When I was looking at how beta works, I have to create an entirely different app with different com.bowengames.xyz, is that correct?

    In the store, you press "upload new application", and there you can select that you want to upload a beta version of it. So yes, it's gonna be entirely new application.

    Does this give you guys any clues? It's a really wide screenshot of the excel table from WP Dev Center.
