MS Edge and Yandex Browser Not Opening, But Processes Show Up in Sandboxie

Sandboxie is a powerful tool that allows users to run applications in a sandboxed environment, isolating them from the rest of the system. However, some users have reported an issue where MS Edge and Yandex Browser do not open, but their processes show up in Sandboxie. In this article, we will explore this issue and provide potential solutions.

When you launch Edge and Yandex Browser, Sandboxie shows their processes, but the browsers themselves do not open. This issue is not limited to a specific sandbox type, as it also occurs in a new empty sandbox. Google Chrome, on the other hand, works correctly in the sandbox.

To troubleshoot this issue, you have tried changing the default apps, reinstalling the sandbox, and making changes to the config. Specifically, you have modified the ClosedKeyPath settings to:

ClosedKeyPath=HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice
ClosedKeyPath=HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\https\UserChoice

However, these changes did not resolve the issue.

This issue occurs every time you launch the browsers.

The expected behavior is that the browsers should launch and function correctly in the sandbox.

The affected programs are MS Edge 134.0.3124.51 and Yandex Browser 24.10.4.824.

You can download the latest version of Yandex Browser from the official website: https://browser.yandex.ru/

The program is installed both inside and outside the sandbox.

No, not at all.

There is no crash dump available.

You are running Sandboxie-Plus v1.14.10.

Yes, you recently did a new clean installation.

No, this issue did not occur in previous versions of Sandboxie.

This issue occurs in a standard isolation sandbox (yellow sandbox icon).

Yes, you can confirm that this issue also occurs in a new empty sandbox.

You are running Windows 10 Pro 22H2.

This issue occurs in a local account (Administrator).

You have Kaspersky Endpoint Security 12.5.0.539 installed.

No, you did not enable any security policy settings outside Sandboxie.

You have attached a trace log file: browser.exe.log
