Met a guy on LinkedIn, now my savings are gone to 'Mountain Effort'. How do I even report this?

I really feel like such an idiot. I met this guy on LinkedIn, seemed so professional, you know? Started chatting about investments, he was so convincing, said he had an 'in' with this platform called 'Mountain Effort Digital Currency Exchange'. Showed me all these 'profits' he was making. I started small, then put in more and more, even took out a personal loan. Now they've blocked my account and are demanding a huge 'tax' to withdraw anything. I've lost about $120,000 USD. My family doesn't even know. i'm based in singapore, and i feel completely lost on what to do. I tried looking up 'Mountain Effort' and it just looks dodgy af. Is there even a point in reporting this? Who do I report to in Singapore or internationally? Any advice on next steps would be a lifesaver.
