  Ah! Sorry for the confusion, you are right that there can be at most one Windows Sandbox running at a time. But Windows Sandbox is based on Windows Containers [1] which can coexist (Defender already uses the same technology, so this must be true), and it seems that the single instance limitation of Sandbox is more or less artificial [2]. I haven't yet seen a third-party attempt to emulate Sandbox but it looks in principle possible.
