Sounds like a failure to resume from S4. Which applies to the system being shutdown or in hibernate. This should not happen, and this is certainly something we test. The flickering you're seeing is drive activity, so it tries to access the drive and then hangs. Try this to confirm:
Right click "Start" and go to "Windows Powershell(Admin)". Type: powercfg -f off
Press "Enter", you will not get a confirmation that it succeeded. It'll give you another prompt, it will give you an error if the command fails. Reboot the PC. Then we'll use the PC normally and see if the issue persists.
Sounds like a plan, please let us know if you have any other questions or concerns!
