Unity 2018 Android builds freezes

Unity Engine
1

Hello everyone,
we have a project that was created using unity 4 and maintained and updated until 5.6, when Unity 2017 was released, we weren’t able to update for unity 2017 due to incompatibly issues when building for android, we didn’t have the time or the capacity to look into it, so we skipped the full year and all 2017 releases

when 2018 was released I was excited to updated especially for the new C#, the project compiled and I was able to run it. However, on android it’s a different story, the project runs ok at first, but whenever an exception is fired the whole app just freezes (doesn’t crash, just complete freeze)

the logs aren’t helpful at all, this was from the logcat

We suspected a library that registers exceptions is involved since the freeze happen on normal exceptions
as an experiment, we tried to create a new project from scratch, exceptions were fired normally and the app doesn’t freeze, I enable the performance reported from Unity services and the problem happened again!

an empty project with only one button to fire an exception and the performance reporter is enabled and the freezes came back

I think the issue is complicated, but if anyone can help we will appreciate it

I was seeing this too after calling LoadLevel or LoadLevelAsync. Disabling performance reporting did fix it, although now I don’t have that feature.

I am seeing this as well. Looks like the same or similar is happening on OSX Standalone: Unity Issue Tracker - [Services][Performance Reporting] Managed exceptions crash OSX standalone build when performance reporting enabled

Any news of a fix or workaround (aside from disabling the performance reporting service)?

I faced the same issue like khallouf , recently i converted my project from unity 5.6.1 to unity 2018.2 in that particle emitter is deprecated so that scene is not unloading deprecated game objects and game will freeze when we are changing our scenes. remove all deprecated game objects and check in android device
