We've recently moved to the latest EO build and have seen the following crash in our production app. No crash dump was produced, just this exception which we logged.

Any thoughts about what may have caused this? It happen as the application was starting up.

2023-03-24 15:22:30,708 [1] ERROR App - Unhandled exception detected

I'm not sure if this helps, but when we tried to close the app we then got a second unhandled exception (which I assume was due to the process crash reported in the first):

Thanks, we've amended our code to include this logging. I'm struggling to reproduce the crash on the bench. If I can, I'll reply to this post. If not, there isn't a lot more any of us can do! :)
