Am I missing something here? I just reformatted my desktop computer and reinstalled my wallet on it, is there something that I've changed on the electrum setting probably?
Look at the fee target which is set to static and it should be changed to Mempool and then you can see the fee is far less since the currently required fee for TX to be included in the next block is 11.1sat/vb.
What you see in below where you pointed out is that you are about to pay 51% as fee from the total amount you are trying to send.
