*Steps to reproduce:*
1 Create new HDRP project (or use any relatively big project you have)
2 Open project and enable Cache Server in Project Settings (connect to working instance of Accelerator, e.g. local one on your machine)
3 In Project Browser do RMB->Reimport All and select Reimport
4 Wait while Editor reloads and becomes responsive, then go to the right lower corner and unfold "Background Tasks" window - there should be "Upload artifacts" progress bar, press "x" to cancel it
5 Then go to Project Browser, select any big folder (e.g. Materials, Textures, Models) and do RMB->Reimport
6 This will create new progress bar in "Background Tasks" window

*Expected results:* added progress bar is Not stuck and Not marked as "Not Responding"

*Actual results:* Wait 10-15 sec and see that added progress bar is stuck and marked as "Not Responding", if you press "x" on it - there will be Scheduler errors thrown.

Sometimes after all these steps when you close the Editor it crashed with:
