If you are mirroring onto your Mac receiver and the only way you can access other windows or applications on your Mac is to close the Mirroring360 session, you will need to disable AirPlay on your macOS Monterey or Ventura.
This situation occurs when you mirror from your device to your macOS Monterey.
Resolution:
On your macOS Monterey, go to System Preferences > Sharing > Disable AirPlay by unchecking the box next to AirPlay.
On your macOS Ventura/Sonoma, go to System Settings > General > AirPlay & Handoff > Disable "AirPlay receiver"
Restart your mirroring session and your issue will be resolved.
