[Bug]: Initial setup loops forever and never installs dependencies (DXVK/VKD3D/Runners)

[D1spell-tech]

Describe the bug

After launching Bottles for the first time, the initial setup wizard starts installing dependencies. The progress bar reaches 100%, but instead of completing the setup it starts over again and repeats indefinitely.

The setup never finishes and I cannot proceed past the initial screen except by pressing "Continue", which restarts the same dependency installation process.

Expected behavior:

• Initial setup should download and install required components.
• Setup should complete successfully.
• Bottles should become usable after the first launch.

Actual behavior:

• Progress reaches 100%.
• Setup restarts from the beginning.
• DXVK, VKD3D and managed runners are never installed.
• Bottles remains stuck in the onboarding/setup process.

To Reproduce

1. Install Bottles from Flathub.
2. Launch Bottles.
3. Start the initial setup process.
4. Wait until dependency installation reaches 100%.
5. Observe that the setup restarts instead of completing.

Additional context

The issue occurs immediately after a clean installation from Flathub.

The following checks were performed:

• Reinstalled Bottles.
• Removed ~/.var/app/com.usebottles.bottles/data/bottles
• Verified GitHub connectivity.
• Verified GitHub API connectivity.
• Verified Vulkan functionality.
• Verified Flatpak permissions.

Despite this, the onboarding dependency installation never completes and continuously loops.
