Hi Jeff,

Thanks for your detailed bug submission and following the template.


If you have not already done so, could you also send logs from your launcher immediately after the error code appears? (Help section of launcher > Send logs button)

You can reply in this thread afterwards to confirm you’ve sent the logs. Thank you advance.​​​​​​​


Logs have been sent (yesterday, actually).


Hi Jeff,


The dev team reviewed this bug and concluded that unfortunately the Shadow app does not officially support ARM processor Windows OS computers ( The Shadow app may partially work but you may encounter various bugs/issues until ARM is officially supported for Windows computers. No further action will be taken on this bug report at this time.
