The given does not correspond to any existing part.

Error message

The given {nameof(assetSidePart.Id)} does not correspond to any existing part.

What it means

PrefabEditorController.RemovePart throws this InvalidOperationException when the asset-side part (wrapped as AbsoluteId(AssetId.Empty, part.Id)) cannot be found game-side via FindPart. It ensures RemovePart only operates on parts actually loaded in the editor game scene.

Solutions

1. Check that the part is currently loaded before calling RemovePart.
2. Refresh the hierarchy viewmodels so ids match the live game-side state.
3. Guard against duplicate removal calls (track removed ids).
4. Catch InvalidOperationException and treat the part as already gone.

Example fix

// before
controller.RemovePart(partViewModel, parent);
// after
var partId = new AbsoluteId(AssetId.Empty, partViewModel.Id);
if (controller.FindPart(partId) != null)
    controller.RemovePart(partViewModel, parent);

var partId = new AbsoluteId(AssetId.Empty, assetSidePart.Id);
if (controller.FindPart(partId) == null) return; // already gone

bool PartLoaded(AssetViewModel p) => p?.Id != null && controller.FindPart(new AbsoluteId(AssetId.Empty, p.Id)) != null;

try { controller.RemovePart(part, parent); } catch (InvalidOperationException ex) when (ex.Message.Contains("does not correspond to any existing part")) { logger.Debug($"Part {part.Id} already removed"); }

When it happens

Trigger: Calling RemovePart with an assetSidePart whose Id was never loaded, was already removed, or whose id no longer matches the game-side AbsoluteId mapping.

Common situations: Double-delete after an undo/redo; removing an entity whose game-side counterpart failed to load; stale viewmodel references after prefab reload.
