[BUG] Starting steamVR always display the Settings Window and 2 other empty windows

[anxest]

Bug description
When I start SteamVR, there is always 3 windows that open next to the steam dock and the Vr View on the computer screen:

• The steamVR settings window, with no title
• An empty black window with the title SteamVR Settings
• An empty gradient window with no title.
  If I close all those windows with my mouse, and try to open the settings again from the steamVR dock, it might open two windows: the one displaying the settings menu, without a title, and the empty one with the title "steamVR Settings".
  Another detail: I can navigate in the settings, clicking on General, Play Area, Dashboad, Controllers, Video, Camera, Startup/shutdown and Developper menus without trouble, but If I try to open the OpenXR menu, the window will crash, and a new empty black window will open with the title "SteamVR Settings" (not sure it's related to the three windows always displaying on startup though).

To Reproduce
Steps to reproduce the behavior:

1. Start SteamVR
2. Watch the 3 windows on the computer screen

Expected behavior
Starting SteamVR with no extra windows, and only
