I think I was hit by a scam on Electrum that I have never seen before

I think I was the victim of a malware on Electrum 4.7.1. I looked for information, but I have never seen anything like this. I sent a transaction to Kraken, to the correct address, but strangely the transaction had a very low fee, different from the one I had set (I set 3 sat/vbyte, it was 0.1 sat/vbyte). So I did a replace-by-fee, but the replace-by-fee sent the funds to a similar address that was not the same one, and now they are going to this address, which I do not know who owns. This is the transaction ID:

f4db8cdf211b53a24a4e9825f46d3b6d0b06d312912d04c5a0fffc8d32e96757

Yes, it is 1.26 BTC. It hurts. It hurts a lot. Thank you to anyone who can help by confirming the scam, or by suggesting a way to check if the funds are safe. Thanks.
