NVDA 2019.3 Crash, liblouis?

Windows 10 Version 1809 (OS Build 17763.1098), NVDA 2019.3.1
I have been noticing this crash when using NVDA with my braille display. Below is the portion of the log. This crash occurs while navigating, can be with arrows, alt tab, object nav. The display is a handy tech. I have not tried navigating with the display itself to see if similar crashes occur.
WARNING - watchdog._watcher (21:43:56.531) - watchdog (6796):

Nothing else after that. I have to press ctrl+alt+n to relaunch.
Any thoughts on this?
