Problem with TeamViewer

In my specific case, running MacOS 10.13.3 (17D47), Teamviewer (v13.1.2991) is not even allowing me to start. I double click after installation, follow and accept any prompts for action on my part. Once installed, I cmd+spacebar (to pop spotlight bar and search) to start Teamviewer.app. The software will briefly flash in my dock and will appear in my toolbar as an active software very briefly and will disappear before I manage to see any UI of any kind.

Hoping for some expert feedback.
