MacBook Pro (16-inch, M1 Pro) with macOS Monterey 12.3.1 and an iPad Air 5th-Gen with iOS 15.4.1 and a USB-C-to-USB-C cable. Occurred while the iPad was switched out of Sidecar into a different iOS app for a few minutes. Both devices had been restarted recently due to troubleshooting Sidecar freezing problems.

Hey user9287432,
Sidecar is a great feature! The first step you'll want to take to resolve this is to update both your iPad and macOS. Updates have released recently and updating could help to resolve this issue. Be sure to back up first!
Update your iPhone, iPad, or iPod touch
How to manually update apps on your Apple device
You'll also want to be sure that both devices are signed in to the same Apple ID and connected to the same Wi-Fi network shown under "Additional requirements" here: Use an iPad as a second display for a Mac
Let us know how it goes.
Take care.

The current stable release of Monterey including bug fixes, is macOS 12.4
Keep your Mac up to date - Apple Support
Keep your Mac up to date - Apple Support
Update your iDevice - current stable release iOS 15.5
Update your iPhone, iPad, or iPod touch - Apple Support
I would start there.
Sidecar error: Unable to connect to [iPad name]. A miscellaneous error occurred (-1010). (OK)
