Launchbox repeatedly launching. Please help

[FALSE]

I've got a weird thing going on where LaunchBox just auto starts on its own repeatedly. 
I'll launch LB, shortly after that it tries to launch again, and again, and again. 
Each instance gives a popup window stating an instance of LB is already running. 

If I launch Bigbox it loads, then LB starts launching itself repeatedly.

In both cases it quickly bogs the system down and I've had to frantically close instanced of LB via Task Manager while they were duplicating themselves.

I've tried rebooting countless times. Ran the installer again. Checked startup apps in windows, setting in LB.

I'm using a pretty standard setup. Like an old 4th or 5th generation I5, 16gb ram and an Nvidia GT970, windows 10.

It was running totally fine two days ago. I've been refreshing my long neglected cabinet. Changes made, messing with led blinky (still cant make it work right), reconfiguring button controls in MAME and Bigbox, added thin 3d printed button inserts in my led buttons. A couple buttons are disconnected, waiting on replacements, but their switches are all connected and work fine when manually toggled.

This is a paid licensed copy of bigbox.

Happy to provide any other info if folks could help me troubleshoot?
