Xbox design lab is down

I take it you are trying to use the Xbox Design Lab? Try to contact support and say you're having trouble with the controller design lab. Or see if there is a support page/email/number on the controller design lab website.

The warranty for Design Lab controllers is 120 days (6 months). You can use this article (Xbox Design Lab and Xbox
Design Lab controller help) for any troubleshooting you need for your controller. If you do need servicing for your controller, you can set it up at https://support.microsoft.com/devices.

They shut down design lab for a time and then brought it back. When they brought it back they removed that gallery.

Here are a couple of links that should help:

If you continue to have issues with the DL controller I would suggest setting up a repair order if it's still under warranty.
