Hi Obbo578,
We have some troubleshooting suggestions that may help to resolve the issue with being able to unable to use AirDrop with a specific user account on your Mac:
"If you can't see the other device in AirDrop
Make sure that both devices are within 30 feet (9 meters) of each other and have Wi-Fi and Bluetooth turned on.
Choose Go > AirDrop from the menu bar in the Finder, then check the ”Allow me to be discovered by” setting in the AirDrop window. iPhone, iPad, and iPod touch have a similar setting. If set to receive from Contacts Only, both devices must be signed in to iCloud, and the email address or phone number associated with the sender's Apple ID must be in the Contacts app of the receiving device.
Install the latest software updates for your Mac and other devices.
Make sure that incoming connections aren't blocked in firewall settings:
- macOS Ventura or later: Choose Apple menu > System Settings. Click Network in the sidebar, then click Firewall on the right. Click the Options button, then make sure that “Block all incoming connections” is turned off.
- Earlier versions of macOS: Choose Apple menu > System Preferences, then click Security & Privacy. Click the Firewall tab, then click the lock
and enter your administrator password when prompted. Click Firewall Options, then make sure that “Block all incoming connections” is deselected."

Cheers!
