50k gone due to malware attack. What should I do?

I know I can't get the money back. I know transactions are irreversible and that no one other than the thief can give me my money back.

My question is about what actions are advisable to take when something like this happens?

I'm asking in the sense of legal procedures, taxes, security, and also perhaps for mental health? (I am based in the Netherlands, btw). Maybe a way to report their site, their twitter accounts, or anything you could think of?

I have been in crypto since 2017, investing regularly and avoided being scammed so many times. But this one was well-thought social engineering that targeted me specifically. And they made a great job at it. I wish they could use such talent for something good.

I am looking at ways to strengthen my digital security, and continue investing and building in the space. But before I completely move on from this, I want to know if anyone has good advice on what to do next.

Thank you.

EDIT: For all the people asking, here is what I know.

I'm still not 100% sure how I got the malware. But it seems obvious now: I am a game/metaverse artist. They reached out to me to work on their game. We had some conversations. They asked me to visit their site, login and download their game. I have done this with lots of clients.

Avast and virustotal says “file is ok” but then it says “potential malware detected” when running it. I block it and delete it.

Next day i get people trying to access my email. I remove metamask. Change all passwords.

3rd day I get someone accessing my 3commas account. They accessed all my emails again, i change all paswords again.

4th day, emails accessed, they signed out my phone so I woulednt see the notifications from opensea while they sold all my nfts. all my funds on metamask are gone.

The -supposed- scammer was actively chatting with me about his game and our job until the moment of the theft.

I'm not sure how they did it. I'm quite a bit shaken. Haven't fully realized what all this means. I'll continue checking comments when I have my thoughts in order. Thanks mostly to the people replying to my original question.
