I launched Windows 10's Sandbox and installed the latest version of Edge Canary. The process seemed to go just fine but I couldn't launch Canary. I tried using the desktop shortcut, the start menu, I even tried shutting down and relaunching Sandbox. It simply refuses to launch from the Sandbox.
1- Launch Microsoft Sandbox
2- From within the Sandbox, go to microsoftedgeinsider.com and install Edge Canary
3- Try to launch Edge Canary ad nauseam. It doesn't work.
I tried Chrome Canary and it launches every time. I've tried Edge Dev and it didn't work. Only Edge Chromium seems to have that problem.
