From the above suspected @jrummell: Hey, would you mind checking the above issue and see if its related to your change ?

Appreciate your help.

Thank you!

Based on the crash it looks like the ExecutionContext is gone. I'll add a check for it.

Add check for null pointer

When resources are freed, asynchronous tasks may fail later and cause
promises to be rejected. However, since the resource is gone, this
crashes. Add a check that the ExecutionContext still exists before
using it.
