I had nearly the exact same error after running the August Windows update. Like many of you I spent quite a bit of time going down the Intel HD Graphics route due to the "Faulting module name: igdrcl64.dll" bread crumb. It turns out that, for me, the ***FIX*** for this issue was to increase my virtual memory from 16GB to 32GB (the same as the total memory of all 8 8GB AMD RX 570 cards divided 2). I cannot say whether it was an DAG/epoch 200 related change, Windows Update, Windows Defender, or Mercury being retrograde that caused it - but I am back up and running!

Initial errors:

1.)  Windows event viewer:
