I have 80.0.320.5 running on two different laptops, each running fully-patched Windows 10. One one laptop, Edge seems to run fine. On the other, it's crashing within 4 seconds of launching (i.e .not enough time to bring up the feedback window).
Is there a crash log dumped somewhere?
you can check in this page:
to see the crash IDs and whether or not they are uploaded
also the crash files must be here: %localappdata%\Microsoft\Edge SxS\User Data\Crashpad
if you are using Canary.
if not, you can find your user directory from this page:
@chris_conley Same observation here. Both Canary and Dev crash/close tacitly on my DELL G7 but not on my Surface Pro.
