App in preview wont start, cannot connect app to debugger


I have problem with my app in SAP AppGyver Preview.

Suddenly I cannot open one of my app, its stuck on first spinner and nothing more. I also cannot connect with this app to debugger to see on which stage its stuck, so I cannot do anything right now with this app.

Anyone else have this problem earlier? Maybe AppGyver team can take a look from barebone perspective?
