Wow, what a bad experience! I almost lost my pen drive! By the way, using Balena Etcher I almost lost my pen drive too.
I had to use "Diskpart" from CMD. I used the commands "list disk", "select disk and "Clean". After that I ran Rufus again using the first option. And now at least my pendrive is back live.
However I still am not able to install LL, even excluding step 3.
I think maybe the problem is the failure on build a bootable device, although Rufus said the procedure was concluded successfully.
