Try an SMC reset:
Resetting the System Management Controller (SMC) on your Mac - Apple Support
If that doesn't work, use a USB mouse to delete both the Magic Mouse and Magic Trackpad from the Bluetooth preferences and then add them again.
You can also try a Safeboot to rule out anything third party from causing the issue. You can Safeboot by restarting the computer and holding the Shift key until you see an Apple and a progress bar.
