Confirmed. App quits instantly on launch. We were upgrading from 5.1.2 because we discovered that in release build, and only in release build, trying to initialise OneSignal on app launch causes it to hang for 1 minute, but now the latest version causes a complete crash

[nan-li]

Thanks for reporting, some changes introduced are deadlocking, we will be making a followup release shortly. Appreciate the quick feedback.

[ihijazi]

Confirming this is happening on my end as well. Any timeline a fix will be released? As we are planning to release an app within the next 1-2 weeks.

Thanks

Hi all, we released Version 5.3.2 as the replacement. Please upgrade to this version instead of 5.3.1 and reach out with any further issues.
