The issue appears to be the vGPU setting. The default is enabled. I created a sandbox.wsb configuration file with the following inside it:
<Configuration>
<vGPU>Disable</vGPU>
</Configuration>
This fixed the issue for me.
Windows sandbox edge and UI not fucntioning, just a plain white square

I have been helped by Jen at Microsoft support, tried all troubleshooting steps, reinstalling, enabling services tied to the program but still nothing works, anyone else having similar issues?

Did you manage to find a solution for that bug? I’m experiencing the same issue and currently trying to fix it.
Thanks a lot,

Robert Wicks 80 Reputation points2025-09-04T10:16:13.59+00:00 The same thing is happening for me. The cursor changes to the text modification cursor when I move the mouse where the URL bar is, so I think the issue has something specifically to do with Edge displaying. The underlying browser seems to be actually running.

Eugene Opanasenko 10 Reputation points2025-10-13T21:40:29.7366667+00:00 I fixed this issue by disabling vGPU from "Group Policy".
Open gpedit.msc, go to "Computer Configuration -> Administrative Templates -> Windows Components -> Windows Sandbox"
Find: "Allow vGPU sharing for Windows Sandbox"
Disable it

Lorenzo PG 0 Reputation points2025-11-17T16:00:15.78+00:00 I had the same issue (possibly connected with Nvidia gpu drivers) and took the annoying habit to keep a copy of Firefox portable in my Download folder, so that I could copy it in Windows Sandbox each time I needed it, start it and browse with it.
Eugene Opanasenko's solution is an easier and better one: it works perfectly for me (though it still sounds more like a workaround than a proper solution, which we would expect to come from Microsoft).
Thanks

2025-09-10T17:37:47.14+00:00 Hi Robert, where did you store the wsb file, and did you overwrite an existing one?
EDIT I'll answer my own question here. It looks like you can create the WSB file anywhere. It essentially becomes a shortcut to launch the Sandbox with those settings set in the wsb file.
per AI answer: You should store a
.wsb(Windows Sandbox configuration) file anywhere on your host machine's local drive, not inside the sandbox itself, and then double-click the.wsbfile to launch the sandbox with that configuration. A common and organized approach is to create a dedicated folder, such asC:\SandboxScriptsor%userprofile%\OneDrive\Sandbox, to store both the.wsbfile and any associated script files. -

David H 10 Reputation points2025-09-13T11:19:46.9866667+00:00 Thanks! This solved the issue for me. For others who may not be aware: you can create the sandbox.wsb file with Notepad and place it anywhere, for example on your desktop.

Jeremy Stewart 20 Reputation points2025-08-26T13:40:23.6633333+00:00 Did the "advisors" completely miss the fact that the OP indicated in the title that this is inside Windows Sandbox??
Happening here also, haven't yet the time to R&R the feature.

2025-08-26T14:35:18.2566667+00:00 I removed and reinstalled the entire feature after repairing and resetting. Same issue.
I installed chrome and that browser also has the same issues as Edge. Installed Firefox and the browser opened fine. Looks like Chromium in Sandbox is borked.

This hasn't helped with anything, before doing this I got it to work a single time, and I have no idea what caused it. Why does Windows have to be so frustrating to work with, my experience with windows 11 has been awful so far..
