Hi! I understand that the Session app on your Linux desktop is not opening—it just keeps spinning. I want to help get this sorted out for you. To start, could you please share a few more details?

1. Which Linux desktop environment or distribution are you using? (e.g., Ubuntu, Fedora, Mint, etc.)
2. How did you install the Session app? (e.g., Flatpak, AppImage, from a package manager)
3. When you say it keeps spinning, does it show a loading indicator indefinitely, or is it stuck on a blank screen?
4. Have you tried restarting your system or reinstalling the app already?

With these details, I can guide you through steps tailored to your setup and the kind of installation you have. Meanwhile, here are some general, simple checks we can do:

### Step 1: Restart the app and your device
- Close the Session app completely (if it’s running in the background).
- Restart your Linux system.

### Step 2: Run the app from terminal to catch error messages
- Open a terminal window.
- Run the Session app from the terminal command line (for example, if installed via Flatpak, use flatpak run im.status.session or run the AppImage directly by navigating to its location and running ./session.AppImage).
- Look at any error messages or logs that appear; they can give clues about what is failing.

### Step 3: Check for updates or reinstall
- If you installed via Flatpak, try updating with flatpak update im.status.session or uninstall and reinstall using Flatpak commands.
- If using the AppImage, download the latest version from the official source and try running it again.

### Step 4: Check dependencies and permissions
- Sometimes the app might require permissions or dependencies not set correctly, especially with Flatpak.
- Flatpak apps are sandboxed; ensure the app has network and file system access permissions as needed.

If you have already tried some of these or if you see specific error messages in the terminal, please share those with me. That will help me provide more precise next steps.

Are you able to try running the app from the terminal and share what it outputs?
