Hey there, thanks for your report! Unfortunately with just this information it's near impossible to diagnose what might be going on. Without any error messages, logs, anything, our guess it just as good as yours.

Please try to get some more information, ideally a reproduction that we can try ourselves that you can add here. That is also why we have the bug report template in place to get all this information. Please provide all the information that is requested in there. Thanks!

I understand the steps you are taking. The real question here is why your app is crashing. There might be a lot of potential causes for that. To figure that out, we're going to need to have some kind of logs or error messages from the Android logs. You might want to look into how to use logcat or add some kind of crashlytics service that will help you catch the errors from the crashing app.

In the issue you linked there is actually a workaround mentioned, did you try that?

Again: it would really help if you could give any more information and ideally provide a minimal reproduction so that we can run it ourselves or look through the code what is going on.

I have solved this by building on a Windows PC. Maybe the problem is more or less related to how my Mac compiles the project. Thank You
