Crash in DatadogExceptionHandler.uncaughtException

[ribafish]

Describe what happened
We've updated the datadog SDK from 1.8.1 to 1.10.0 and started getting reports in crashlytics about a crash in com.datadog.android.error.internal.DatadogExceptionHandler.uncaughtException (DatadogExceptionHandler.kt:48).

Stacktrace is:

Fatal Exception: java.lang.InterruptedException
       at java.lang.Thread.sleep(Thread.java)
       at java.lang.Thread.sleep(Thread.java:442)

and the com.example.App.setupRxErrorHandler$lambda-1(App.kt:127) code is:

        RxJavaPlugins.setErrorHandler { e ->
// ****** Checking for different types of exceptions and handling them accordingly, before getting to the part that's in the stacktrace above ******
            if (e is IllegalStateException) {
                // that's a bug in RxJava or in a custom operator
                Thread.currentThread().uncaughtExceptionHandler
                        .uncaughtException(Thread.currentThread(), e)   // ***** this is line 127 *****
                return@setErrorHandler
            }

Steps to reproduce the issue:
