Short description of error
Pressing the shortcut Shift + R (voxel grid preview on the viewport inside Sculpt Mode) exits Sculpt Mode if the object has a Multires modifier with at least 1 subdivision.

Exact steps for others to reproduce the error

  1. Load Factory Settings
  2. Add a Multires Modifier to the default cube and press "Subdivide" so it has at least 1 subdivision level
  3. Enter Sculpt Mode and press Shift + R (default shortcut for previewing the voxel grid in the viewport)

Expected behaviour: we see the interactive voxel grid
Current behaviour: we return to Object Mode

Note: this doesn't happen if we add the modifier directly inside Sculpt Mode and press Shift + R. So it only happens if we enter Sculpt Mode and the object has the Multires + 1 or more levels.

Well, voxel_size_edit_poll uses object_remesh_poll which doesnt succeed. Meaning you cannot actually remesh with an active multires modifier.
If the operator poll fails, it will fallthrough to Repeat Last which is also mapped to ⇧+R -- which in your case does sculptmode toggeling again.

And since there is also T76655: Sculpt Mode: Edit Voxel Size hotkey conflict -- for which there is a patch ready, see D7726, I think we have to close this one.
