This PR is only a temporary fix.
If ScheduleMode.Run is used, Assertion failed on expression: 'jobData->range.numJobs == 1' is logged.
Also even ScheduleMode.Single is selected, job runs in paralell.
So following is my solution.

public static unsafe void Execute(ref JobWrapper<T> jobData, IntPtr jobData2, IntPtr bufferRangePatchData,
    ref JobRanges ranges, int jobIndex)
{
    if (jobIndex==-1)
    {
      
        JobsUtility.PatchBufferMinMaxRanges(bufferRangePatchData, UnsafeUtility.AddressOf(ref jobData),
            0, jobData.ChunkArray.Length);
        for (int index = 0; index < jobData.ChunkArray.Length; ++index)
        {
            var chunk = jobData.ChunkArray[index];
            jobData.JobData.Execute(chunk);
        }
        return;
    }
    while (true)
    {
        if (!JobsUtility.GetWorkStealingRange(ref ranges, jobIndex, out int begin, out int end))
        {
            break;
        }

        JobsUtility.PatchBufferMinMaxRanges(bufferRangePatchData, UnsafeUtility.AddressOf(ref jobData),
            begin, end - begin);

        var endThatCompilerCanSeeWillNeverChange = end;
        for (var i = begin; i < endThatCompilerCanSeeWillNeverChange; i++)
        {
            var chunk = jobData.ChunkArray[i];
            jobData.JobData.Execute(chunk);
        }
    }
}
