ID 559479 - Nuke Assist crashes whenever a Viewer is created

Problem summary:
Nuke Assist crashes whenever a Viewer is created
 
Customer reported version:
Nuke Assist 14.1v1
 
Customer reported platform:
Windows 10
 
Steps to reproduce:
1) Launch Nuke Assist.
2) Create a Viewer node in the Node Graph, and observe Nuke Assist's performance.
 
Expected behavior:
A Viewer node should be created.
 
Actual behavior:
Nuke Assist crashes when a Viewer is created from the Tab menu, via Python/TCL, or when pressing the number keys when a Viewer does not already exist.
 
A Viewer node can be pasted into Nuke Assist successfully, but double clicking the node will cause Nuke Assist to crash.
 
Workaround:
Opening the .nk script inside a text editor and manually including an additional Viewer seems to work, but it's possible other issues could occur as a result:

Viewer {  frame 1  frame_range 1-100  monitorOutOutputTransform rec709  name Viewer1  selected true  xpos -40  ypos -9 }
