Create cylinder ->[possible] Crash (Fixed)

When creating a cylinder.
Visual tools -> Cylinder
LMB+drag for [base] Radius 1
When moving mouse for "Length" press ctrl+LMB and move mouse = Unhandled Exception. (repeatable)
(NOTE: I had meant to actually press shift+LMB for Radius 2 size change)

A need to then end NVIL process via windows task manager.

Have checked against new default config file with same result.

error log:- error log removed, no longer needed.
