Hi there, @Zinn. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention. I'm sorry to hear that your new Luxe is still crashing itself suddenly. I understand how annoying this can be, I will do my best to help you with this!

As a first approach, I'd recommend trying the following steps to make sure your heart rate is working as heart rate reading is key to get your sleep data accurately:

• Switch the Heart Rate settings from On to Off and manually sync your watch. To switch the heart rate settings on your Luxe, from the main screen of your Fitbit device, open the Settings app > Heart Rate > tap to turn the setting OFF.
• Once it's done, manually sync your Luxe. To do so, open the Fitbit app, tap on the Account icon, tap on your Fitbit device's image and tap on "Sync Now" 
• Next, switch it from Off to On and manually sync your Luxe once again. 
• Once it's done, restart your Luxe.
• Next, confirm that your tracker is snug on your wrist (the lights shouldn't be visible). We also recommend when you're not exercising, wear the tracker just above the wrist bone.

Also, for more detailed information, see What factors can affect my heart-rate reading on my Fitbit device? 

With that in mind, I recommend considering the following in order to get sleep stages:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep with my Fitbit device?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.
