is Niotron alive? Problem with launching the finished apk

I created an application, and everything works through the companion. But when I compiled the apk and installed it on my phone, the application does not start completely. I see a blank screen and nothing else, as if Screen1 is completely empty.
I created the application from scratch using only the ready-made NavigationDrawer template. I also used the SimpleSqlite extension.

provide the aia file for debug

List variable is empty so the recycler view cant work with empty list u must load data before calling rycler view thats happning your screen 1 is blank

That’s surprising. Why does everything work through Companion, but not in the apk?

Capturing device logs might be helpful to find out the actual issue.
