I have a dude,  if you import a private key in electrum, I have verified that in your Electrum version (windows 10 in my case, W11 idk),  if you import a private key, window title shows  [imported]  next wallet name. Your screenshot is not showing that but I didn’t deep into it. What I mean is that screenshot is manipulable. If someone intends to help, at least be sure that it is not a scam. That has  been my first impression reading your post.
