I ´ve been scammed, my wallet compromised... But the assets are still there although I cannot move them now!

Hi guys! I have been scammed in one of the many “official” telegram group which I thought It was really the official. Yes, I know, never give your phrase to anyone. I just learned It the hard way. Be careful! Anyway, the weird thing is that they didn’t steel the coins! My assets are still there both BSC and ERC20, althoughI can’t transfer them now! Tried many times and always gave me a transfer error (although the GAS fees are spent) It’s like they modified the token code or the script or something in order to block them in the wallet (I’m not sure if that’s even possible) … really very strange. Anyone knows something about this? Thanks!!
