Welcome to the Fitbit community, @zajonc!

Sad to hear you're having issues with your Charge 5. As a first approach to hopefully get things fixed, I'd suggest restarting it. Before doing so you should make sure you've synced your device to not lose any data tracked so far. Also you should verify that the charging contacts on your device are clean and the charging pins on it's charging adapter are clean as well and can move flawlessly. In doubt, please have a look here:

Why isn't my Fitbit device's battery charging? 

Next please closely follow these instructions as timing is crucial for this procedure:

1.) Connect your Charge 5 to the charging cable which has to be connected to a reliable power source.
2.) Press the button located on the flat end of the charging cable 3 times within 8 seconds(!), holding each press for about 1 second(!).
3.) Wait around 10 seconds until the Fitbit logo appears on your device's display.

I'd like to point out that it sometimes requires more than one attempt to restart Charge 5. So, before throwing the towel, please give it another try.

If that really won't work for you, please try if changing your device's clock face will get it back to working order. Here's how to do that:

reboots drain the battery, I pluged it onto charger, and it goes fuel it up, I will check after recharge
