What happens if Vanguard goes bust?

As an investor, I'm naturally concerned about the stability of the companies I entrust my money with. So, I must ask, what would happen if Vanguard, a major player in the financial services industry, were to go bust? Would my investments be safe? Would I lose everything I've put in? It's crucial to understand the potential implications and have a contingency plan in place, just in case. So, could you please elaborate on what might happen in such a scenario?
