Maya crash with locked CVs and new UV Set

[morinnicolas8944]

The following sequence causes Maya 2025.1 to crash every time.

• Create a polygon
• Select its vertices
• Select and lock all CVs in the Channel Box
• Select one of the locked vertices in the Viewport and try to move it (It doesn't move and we get the Warning message "// Warning: One or more components are locked and cannot be modified." in the Script Editor, as expected.)
• Select the Object
• Open the UV Set Editor and add a new UV Set
• Render with Maya Software renderer
• Crash

The order [Lock CVs -> Try to move vertex -> Create UV Set] is important. Creating a UV Set before trying to move a locked vertex will not cause a crash.

Note: I also report this bug with the automated bug reporting that pops up after the crash.

Thanks for posting this. I can reproduce it as well.  Getting this logged for a future fix.

Cheers!
