While I haven't been able to run the tests, I do have some feedback that may help pinpoint the problem. The last several months I've left iCUE installed on my system, but have prevented it from running, including (most importantly) the Corsair service. I've found that even with iCUE closed, if the Corsair service is running, the crashing problem will occur.
Unfortunately, while I would like to help out more, I can't risk these crashes happening on my PC as I use it for streaming, and it tends to be more likely to crash when I'm live.
