I would look at it as a great thing, it seems your only drive was making money before which is pretty sad by itself.
I'd first secure your money against inflation by investing 80% of it in safe assets (Real-estate, ETF's, investment contracts with reasonable target yield,...)
That should shield your wealth from inflation while making highly diversified returns in not very risky assets. Any private banker will be able to set those up for you.
There's also Liqid.de if you don't like bankers but private banks provide super cheap loans which can is helpful to leverage.
After that you should find out what you genuinely like and what you don't like by listening to your feelings and eliminate what you don't like and do more of what you really like. At some point that will roll into a new passion and new career.
For me, I just realized that I can't live without being an entrepreneur because all other career choices have too much certainty and boredom.
Happy to chat if you need some pointers
