Hello - this isn't very clear, and we certainly haven't heard of cases of crashing on app startup. We're not able to reproduce any of this within any of our sample apps. Would you please post a sample project which demonstrates the issue you're having?

Seems related to issue fixed in v3.7.3

Hi, @mdakram. Did v3.7.3 fixed the problem?

Hi, @mdakram. I am going to close this issue then. Feel free to reopen it if you get crashes again.

Thank you.

Now I'm on v3.6.4 and everything is working fine.

Hi, @Phanith-Fe. I am testing your sample project in my phone and simulator and I don't get a crash. I tried v3.7.2 and v3.7.3 using an iPhone 6+ and iOS 11.2.2. In your video as soon as you open the app and scroll you get the crash is it consistent?

Hi, @fabian-guerra
It's not always crash, but most of the time, it crash.
Is it a phone or cpu model related? I'm on iPhone 5s, with iOS 11.2.2.
