**System Information**
Operating system: Win 10
Graphics card: 1050 ti
**Blender Version**
Broken: 3.2.0 Alpha
**Short description of error**
Empty vertex group was added to mesh in object mode without weight assigning and modifiers in stack are using this vgroup.
Somehow some modifiers follow restriction and others don't. But if you assign zero weight for this vgroup in edit mode, then all modifiers are limited in execution as expected.
For example, open file and enable viewport rendering for every modifier in stack.

Cast
Curve
Decimate
Lattice
Smooth
Smooth Corrective
Smooth Laplacian
Weld
Wave
**Exact steps for others to reproduce the error**
# Open new General template
# Add monkey
# Create new vertex group, but don't assign any vertices or weight
# Add Smooth modifier
It should not deform mesh, because of empty vertex group, but it does
