We can not repro it for now. Stack trace from our crash reports:

Hi Andrey, 

I will need more details on the scenario in which the exception message occurs. Send me a sample app in which the issue happens, so I can further research this. 

If you do not want to attach the ticket in the forum, open a support ticket and attach the project to it. To reduce the file size, delete bin and obj folders and archive the project.

Hi Didi, I will try, meantime the stack trace says nothing to us, looks independend in Telerik Maui.

We have a RadCollectionView with the multiple groups, happened randomly by our crash logs

Telerik.Maui.Data.ParallelDataEngine.GenerateBottomLevelsFromSourceParallel(ParallelState state)
Telerik.Maui.Data.ParallelDataEngine+<>c__DisplayClass117_0.<BeginParallelProcessing>b__0()

Hi Andrey,

I will need a sample repro project and exact Telerik and Maui versions you use in which the issue happens. Also include steps to reproduce the issue and on which platform(s) the crash happens. 

Thank you in advance.
