My 'broker' is asking for a 'network upgrade fee' to release my crypto profits. Is this legit?

Hey everyone, I'm really freaking out. I got into crypto trading a few months ago, found this platform on Instagram, you know how it goes. Started small, then they assigned me a 'broker' who was super helpful. I put in maybe 8,000 euros over time, and they showed me my 'profits' were huge, like 25,000 euros. I tried to withdraw a few days ago, just 2k to test it out, and suddenly they're saying I need to pay a 'network upgrade fee' of 15% of my total balance first. They say it's because of new blockchain regulations and it's temporary. It has to be paid in crypto, upfront. I'm in Marseille, and I've never heard of anything like this. My bank, Crédit Agricole, said they can't help with crypto transfers. Is this a normal thing? Or am I being scammed hard? I feel so stupid right now.
