BreakoutProcess option does not work when opening files directly or using context menu options

[soleera]

Describe what you noticed and did

Steps:

• Install VS Code unsandboxed and with the context menu option enabled.
• Setup a sandbox (any type) with BreakoutProcess=Code.exe
• Create a text file in the sandbox and try to open it by either double-clicking or right click > "Open with Code"
• VS Code attempts to start in the sandbox despite being a breakout process.

Notes:

• Opening via right click > "Open with..." > "VS Code" works as expected
• Opening via the command line (e.g. PS>/path/to/file.txt) works as expected
• Issue persists even when setting BreakoutProcess=* or BreakoutFolder=*
• Issue does not occur when using DisableForceRules=y
• Even when running VS Code unsandboxed, if the current workspace has been set to trusted and you attempt to open the sandboxed text file, processes started by this action will still cause this issue (e.g. dozens of git.exe processes suddenly spawn inside the sandbox)

I believe this is the same issue as #1883.

Log: vscode_sandboxie_open.zip

How often did you encounter it so far?

Always

Affected program

VS Code, git, krita, inkscape, ... (likely program-agnostic)

Download link

https://code.visualstudio.com/

Where is the program located?

The program is installed only outside the sandbox.

Expected behavior

when set as a BreakoutProcess, the process should not be sandboxed.

anyone else with that problem?

Steps:

• Install VS Code unsandboxed and with the context menu option enabled.
• Setup a sandbox (any type) with BreakoutProcess=Code.exe
• Create a text file in the sandbox and try to open it by either double-clicking or right click > "Open with Code"
• VS Code attempts to start in the sandbox despite being a breakout process.

When I opened the document this way, Code.exe crashed and the dump file was created in sandbox. (HOST, Windows 10 22H2)

I will also try it in a virtual machine. (Hyper-V, Windows 11 22H2)

I have a similar issue, and especially the git.exe will be forced into sandbox.
