Adding a sandboxed v2ray precompiled binary to my application

Greetings! I want to add my pre-compiled binary of v2ray to my application so I can activate it in background as a proxy and run stuff through it.

I've codesigned it via: codesign -s - -i production.myproject.v2ray -o runtime --entitlements v2ray.entitlements -f v2ray

Contents of entitlements file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>com.apple.security.app-sandbox</key>
	<true/>
	<key>com.apple.security.files.downloads.read-write</key>
	<true/>
	<key>com.apple.security.files.user-selected.read-write</key>
	<true/>
	<key>com.apple.security.network.client</key>
	<true/>
	<key>com.apple.security.network.server</key>
	<true/>
</dict>
</plist>

Originally I ran it like this without sandboxing from my main target app:

        guard let v2rayPath = Bundle.main.path(forResource: "v2ray", ofType: nil) else {
            throw NSError(domain: "ProxyController", code: 1, userInfo: [NSLocalizedDescriptionKey: "V2Ray binary not found in bundle"])
        }

        let task = Process()
        task.executableURL = URL(fileURLWithPath: v2rayPath)
        task.arguments = ["-config", configURL.path]

        // Redirect output for debugging
        let pipe = Pipe()
        task.standardOutput = pipe
        task.standardError = pipe```


And it ran flawlessly. Now it refuses to start. Any help, pointers or examples of such usage will be greatly appreciated
