Short description of error
Blender instantly crashes when pressing the Ctrl key with the Measure Tool selected, as well as in other situations that I haven't been able to efficiently pinpoint. This seems due to the presence of a certain Curve object in the scene: if I delete it the problem cannot be reproduced anymore.

Exact steps for others to reproduce the error

Open the attached .blend file and activate the Measure Tool (already done in this file)
Hover the pointer on the 3D viewport
Press Ctrl with the Measure Tool enabled
Blender crashes

Another way to reproduce a similar insta-crash condition with the same file is clicking on the "Add Cube" tool icon on the left toolbar and then hovering the arrow on the 3D viewport.

Can confirm, crash on BLI_assert_unreachable()

This is most likely related to #91734 as well. The measure tool isn't necessary to crash the file here. Load the file, select the box selection tool, select one of the curve objects and start to move around and attempt to snap somewhere with CTRL.

Indeed a duplicate of #91734 (Crash snapping mesh if a beveled curve is present), will merge these reports.
