When I start the app, "teamviewer meeting.app check" opens and the display is at 50%, CPU usage goes to 100% for "XprotectService" and this state remains.

Until I close the start dialogue with X and close "XprotectService" in the activity display.

Programme not usable.

Teamviewer Remote Support has always worked perfectly. 

Kaspersky Endpoint Security is installed
