Hi there!

Thanks for reporting this! add the following code to line 918 of BurstSolverImpl.cs:

Quote:dequeueHandle.Complete();

Should look like this:

Code:
var dequeueQueryResults = new DequeueIntoArrayJob<BurstQueryResult>()
            {
                InputQueue = resultsQueue,
                OutputArray = results.AsNativeArray<BurstQueryResult>()
            };

            var dequeueHandle = dequeueQueryResults.Schedule();
            dequeueHandle.Complete(); //<---- new line

            var distanceJob = new CalculateQueryDistances()
            {

That should fix the issue. Let me know how it goes!
