Maya crashes when opening file with Hypershade window already opened

Issue:

Maya crashes when opening file while already having the Hypershade window opened.

Causes:

• Code in the userPrefs.mel file is set to a value of 1.

The line of code causing the crash is: 

-iv "minorNodeTypesDisplay" 1

• Unassigned materials might cause the crashing behavior

Solution:

To solve the crashing behavior of Maya:

• Change the file userPrefs.mel

1. Find theuserPrefs.mel file in C:\Users\<user name>\Documents\Maya\2019\prefs
2. Open the file with a text editor and find the line -iv “minorNodeTypesDisplay” 1
3. Change the value to 0. The line should look like -iv “minorNodeTypesDisplay” 0
4. Save the file and restart Maya.

• Execute a “Delete Unused Nodes” in the Hypershade

1. Open the Hypershade in Maya at Windows > Rendering Editors > Hypershade
2. In the Hypershade window, go to Edit > Delete Unused Nodes.
3. This function will delete all unassigned materials from the scene file.
4. Save the scene.
