Hey, sorry to post another problem.

Our product has been released under 2.2.6 now for 5 months now (WebAssembly) and we have had almost no problems. I don't think I've seen a single crash.

Locally, after upgrading to 3.0, while running our app in the editor, I'm getting random crashes where the Unity editor just disappears. I'm not sure where to get the proper logs to see what is going on.

If I try to run our Android build on my Samsung tablet, I get the same crashes. I did get a stack trace from LogCat. The crash seems to be a null reference in Noesis.View.Noesis_View_Update.

The crash usually happens within a minute or two of running the application, so it is not hard to reproduce.

Can you point me in the right direction to figure out what is going on or how to properly debug this? I know in some other cases the upgrade to 3.0 has exposed bad things I was doing that were just working accidently under 2.2.6, so perhaps this is similar.

All crashes are considered bugs in our product, in case of user error we should provide the appropriate error message and continue without crashing.

I created a ticket in our bugtracker to track this crash: #1749
We can continue the discussion about the crash there.
