AirDrop not working from laptop to iPad

M1 Macbook Pro w/ OS 15.3.2 (so up-to-date); 6th gen iPad, iOS 17.7.5

Up until 5 days ago, AirDrop worked just fine between all my devices. Then, for no apparent reason, the iPad stopped seeing the laptop. All permissions are set properly, Bluetooth is on and they are on the same wifi network. The iPad sees the laptop and will sent TO it, but will not receive FROM it. The laptop sees the iPad, and will attempt to send, but never gets a positive response. This happens whether the VPN on the iPad (SurfShark) is on or off. Both devices are turned off every evening and restarted every morning. All devices are on the same Apple ID. The iPad will receive from my iPhone 7+, but not from the laptop.
