Short description of error
If I create a curve such as a circle and create a text object set the curve in "Text on Curve" in the object data properties blender crashes

Exact steps for others to reproduce the error

Add Text
Add a curve
In the Text Object Data Properties, go to {nav Font > Transform} and set the Curve in Text on Curve

I can confirm the crash:

Exception thrown: write access violation.
r_vec was nullptr.

It happened sometime between 7d7dd66ba7 (Feb 24) and c486da0238 (Apr 23)

I will bisect but confirming for now.
