Hi there! I understand you're seeing a "Something went wrong with that page" error when trying to print anything from your desktop using the Toybox app, but the app itself seems to be working fine otherwise. Let's try to get this sorted out.

A few questions to help me understand better:
- Is this error happening when you try to print from the Toybox app only, or from other apps on your desktop as well?
- Have you recently updated the Toybox app or your Windows 10?
- Are you trying to print via a network printer or a directly connected printer?
- Have you tried restarting the app or your computer already?

While you answer, let's start with some basic troubleshooting steps:

1. Restart the Toybox app and your computer to clear any temporary glitches.
2. Check your default printer settings:
- Go to Settings > Devices > Printers & scanners and make sure your preferred printer is set as default.
3. Update your printer drivers:
- Printer driver issues can cause printing errors. Visit your printer manufacturer’s website to download and install the latest drivers compatible with Windows 10.
4. Try printing a test page:
- From Printers & scanners, select your printer > Manage > Print a test page to see if the issue is with the printer or the Toybox app.
5. Clear the Toybox app cache or reinstall it:
- Sometimes app data gets corrupted. Uninstall the Toybox app, reboot your machine, then reinstall it afresh from the official source.

If after these steps the problem persists, it may help to check log files or any specific error codes the Toybox app reports when printing fails. Also, let me know what kind of printer you have and how it's connected.

Does that make sense so far? Any details you can provide about your setup will help me guide you better!
