Cesium crashes we noticed on Oculus/Android UE 5.3 Cesium 2.0.0

Cesium for Unreal
1

We’re getting these from the Oculus dashboard but we’re not sure what these are. Thanks

Crash Reason

SIGABRT:libUnreal.so:task_base.h:void async::detail::continuation_vector::flush_and_lock<async::detail::task_base::run_continuations()::{lambda(async::detail::ref_count_ptrasync::detail::task_base)#

Does it still occur on Cesium 2.2.0? (latest)

Also, what was happening during the crash? Initial level loading? Switching level? Randomly in the middle of play?

@Brian_Langevin these crashes were happening in v2.0.0
We tested on v2.2.0 in staging and so far did not see a similar crash. We’ll see if these happen on Production in a couple of days and report back
