Copying a folder creates the target directories on the storage before their cache entries exist, so while the files inside are written the parent of the target path can not be resolved yet. With per-user keys the encryption stream needs the access list on every write, so the unguarded $userFolder->get($parent) made every folder copy fail with a NotFoundException. Walk up to the closest ancestor that is known to the cache instead. Shares only exist on cached nodes, so its access list is the one that applies and the share keys of the recipients are still created when copying into a shared folder.
