Discord fails to open after installing in a standard sandbox and exiting Discord once (+ConsoleInit error at install)

[axolul]

Describe what you noticed and did

Installation of latest DiscordSetup.exe inside a Standard Isolation Sandbox (through sandboxed Windows Explorer) works and Discord installs itself succesfully. During the installation, two error messages appear: "gpu_encored_helper.exe: SBIE2205 Service not implemented: ConsoleInit (C0000D4)". I don't know if this is relevant to the main problem. Picture attached:

After installation, Discord opens itself automatically for the first time succesfully. After exiting Discord completely through the tray icon (confirmed through Sandboxie that all Discord processes are closed), any opening of the Discord application fails after like a second from clicking. Discord updater window shows and the updater process shows in the Sandboxie view. Then the updater window exits abruptly and updater processes close themselves.

Discord can't therefore open itself after exiting at least once, while installed completely inside the Standard Isolation Sandbox. Sandboxie blocks something during the opening update check of Discord.

I disabled Discord's hardware accelleration during the first open after install, but it doesn't seem to be the culprit. Discord's dll injection for screen sharing was also disabled before first exit.

This initially started with an established Discord installation, which probably means either something in the Discord Updater, or Sandboxie, changed recently (last month or so).

I also tried to switch to virtualization scheme v2, but it didn't help.

Thank you for the suggestion! However, this issue is related to the official, non-portable Discord version.
