If I split the loop up in smaller chunks, like 64 iteration each and them separating them in time they all run without crash, this implies some sort of memory issue, I had a look at the native code and there seem to be a sync task in there, even though there is a wait state I am thinking maybe that is the core problem, that it cannot do it in the async task... let me know if you need any help, test or feedback as I can run updates really quickly over here and help you test it and see if it works.\r\n\r\nI have also had problems (after initiating the first iteration of 512, even if they work in chunks) to access only one decodeNumber, as it crashes immiditakey concurrently efter that..\r\n\r\nThanks for your attention",
