The issue is specific to system settings, or due to a third party software installed in the system.
Many products in MATLAB rely on connector to maintain certain states. The connector creates and uses sockets. These sockets are being closed or altered by a third party software installed in the system, or specific system settings, due to which the CPU is spinning.
As the issue is system specific, you can try the following troubleshooting steps:
1) Change the power settings to High performance. To do this, open Power Options by clicking the Start button, and then clicking Control Panel. In the search box, type power options, and then click Power Options. Under Select a power plan, click Show additional plans, and then click High performance.
2) Download and run MSI Afterburner system utility to boost MSI graphics card. Please refer the link for more details on solving High CPU usage:
3) As a third party software is closing the sockets used by MATLAB connector, try killing processes (in Task Manager) which are of no use and are running in background.
If the above troubleshooting steps do not help resolve the issue, then the only workaround is to kill the MATLAB process, and restart the session.
