PWAs fail to launch on my WoA (Arm64) environment
Since PWAs work in the retail version of Edge but fail in Edge Dev, this points toward a possible issue with the Dev build or its PWA profile data rather than your Surface’s ARM64 hardware.
I’d try these steps:
- Update Edge Dev to the latest available build and check whether the issue persists.
- Test launching a PWA from edge://apps and compare it with the taskbar shortcut.
- Create a fresh Edge Dev profile and install one PWA to see if the problem is profile-specific.
- Check whether the installed PWA shortcuts still point to the correct Edge Dev executable.
- If it still fails, capture the exact build number and submit a report through Feedback Hub, including the fact that Figma launches successfully through an in-app link.
Since you’ve already tried repairing Edge Dev, testing with a clean profile is a useful next step before reinstalling everything. For general technology tips and digital resources, you can also explore helpful online resources.
Thank you for your response.
I have checked following items:
A. I am using Edge Dev version 158.0.4344.0, which is likely the latest version. (Details regarding Windows, etc., will follow.)
B. As previously mentioned, I have already tried a repair installation, but it made no difference.
C. The issue does not occur on an x64 machine with a nearly identical configuration and profile.
D. Launching PWAs via `edge://apps` does nothing; they fail to start. The same applies to attempts to launch them from the taskbar, Start menu, or desktop shortcuts.
E. I created a new Edge Dev profile—with no extensions installed—and registered sites like microsoft.com and Google Calendar as PWAs; however, the issue persists, and the PWAs still fail to launch.
F. I created a desktop shortcut via `edge://apps` and verified the target of the `.lnk` file.

Edge Dev (Main Profile): PWA fails to launch
"C:\Program Files (x86)\Microsoft\Edge Dev\Application\msedge_proxy.exe" --profile-directory="Profile 1" --app-id=eocafagfdlbogdgjnjmoehjhjfnnpjln --app-url=https://www.microsoft.com/ja-jp --app-launch-source=4
Edge Dev (Clean Profile): PWA fails to launch
"C:\Program Files (x86)\Microsoft\Edge Dev\Application\msedge_proxy.exe" --profile-directory="Profile 13" --app-id=eocafagfdlbogdgjnjmoehjhjfnnpjln --app-url=https://www.microsoft.com/ja-jp --app-launch-source=4
Edge Retail: PWA launches correctly
"C:\Program Files (x86)\Microsoft\Edge\Application\msedge_proxy.exe" --profile-directory=Default --app-id=eocafagfdlbogdgjnjmoehjhjfnnpjln --app-url=https://www.microsoft.com/ja-jp --app-launch-source=4

G. In this state, simply changing the path from the Edge Dev directory to the Edge directory for `msedge_proxy.exe` allows the application to launch via the shortcut.
H. The file "C:\Program Files (x86)\Microsoft\Edge Dev\Application\msedge_proxy.exe" does exist.
I. While testing the above, I noticed that immediately after registering a site as a PWA in Edge Dev, the PWA window does not open. In the retail version of Edge, the PWA opens and displays a dialog (e.g., for pinning to the taskbar), whereas in Edge Dev, the PWA fails to open entirely.
Taking all of this into account, it appears that the issue is not related to specific profiles or extensions, but rather to the behavior that occurs after `msedge_proxy.exe` is executed.
I will submit this information to the Feedback Hub.
