Hello. I need help with export game with mono/c#. I create simple project with one c# source code file. When I run in editor it works fine. But when I start exported app it crashes.

I'm using Macbook air with installed Godot-mono 3.3.3, mono 6, .Net Core 3.1

Welcome to the forums @Tencry! Are you getting any errors in the Godot console? If so, can you post what the error is you are getting, either in a screenshot or by pasting it here in a code block (see this post for guide on formatting).

There is no problem in Godot editor. I have problem with exported app.

Screenshot here

But if you open the app from the console/terminal does it show any errors? Even exported games generally will print errors to the console, you just need to run it from the console in order to see them. If the console/terminal reports errors, it may help indicate what the issue is.

Thank you for the support. I didn't even think about it. :) I find Mono's logs. I think my mono configuration is wrong and needs to be fixed as described in this doc.
