System Information
Operating system: Microsoft Windows 10 Professionnel
Graphics card: Nvidia Gefroce RTX 2080 Super

Blender Version
Blender 3.0.0, hash: f1cca30557 , branch: master

Seems like it was wrong since the beginning in d6891d9bee

Short description of error
Blender crash when we use bpy.ops.constraint.apply(constraint="Transform Cache") when there are no constraint to apply instead of raising an error.

Exact steps for others to reproduce the error
Open a scene with a cube and run bpy.ops.constraint.apply(constraint="Transform Cache") in script mode

Seems like it was wrong since the beginning in d6891d9bee, still setting to High prio since it is a crash in a recent feature.

It actually happens not only with the new operators, but also with the old ones like bpy.ops.constraint.delete(constraint="Transform Cache").

It actually happens not only with the new operators, but also with the old ones like `bpy.ops.constraint.delete(constraint="Transform Cache")`.

Oops, sorry, true.
