macOS Monterey 12.3 Bluetooth connection problems since update

Upgrade to Monterey 12.3 couple days ago on my MacBook Air 2020. Since then, my bluetooth headphones and BT mouse are lagging, randomly disconnecting and reconnecting every few minutes or so. As this has never happened before the upgrade, I thought it was quite unusual. Anybody else with similar issues or any fixes?
