Hi
Feel free to restart the device manually: How do I restart my Fitbit Device?
When able to get into the settings, It's possible to factory reset your Versa*
All data on the tracker will be erased, and the the tracker will be required to be relinked to the account afterwards.
From the Fitbit Article*
Factory reset your watch to erase apps and all personal data from the device, including credit or debit cards you added (on watches that support Fitbit Pay). If you want to give your watch to another person or wish to return it for a refund, first complete a factory reset:
On your watch, open the Settings app () > About > Factory Reset.
