Assign Activity(2025.10) fails to assign null (Nothing)

[Yoichi]

This is a bug report.
Although this issue is already reported in some topics, Assign activity in the latest stable Studio 25.10.4 still fails null assigning.

VB

C#

As Assign activity is included in Default activities, there is no way to avoid it except modify workflow, for example using MulitpleAssign activity or CType() etc.

Hope to fix this in the next stable release.
