removing the rb from the plugins folder has resolved the crashing
Apart from the extension needing to be compatible with SU2019Pro, which I am not sure of as I do not use it. What method did you use for installation? From the sounds of it you copied and pasted the *.rb file into the SketchUp folders. If so, this the wrong approach, you need to install it using the Extension Manager, also uninstall / remove it using the Extension Manager.
Cudos for trying to be more efficient though!
