Thought I'd better let you know that despite repeated attempts, the Developer Build freezes Windows within a few minutes of launching Edge. The only solution is a forced reboot. I'm using a Huawei Matebook X Pro 2019, with Windows 10, i7 chipset and Nvidia graphics card.
Sorry for the late reply. Have you retried this in more recent days? If not, the Microsoft Edge Insider Build Dev Channel has had numerous updates since this was posted and it should work better for new installs.
