I am having the same issue for forge 1.20.1, both releases, but NOT for 1.20 and any other version below that.
@Always needs help did you by any chance unzip the whole thing, including the weird conf folder? This seems extremely likely to be a virus. I opened the nginx.conf file from the conf folder in a text editor and this file reads and executes the png file from that same folder. I assumed the exe file would set it all up and allow the hidden code from the image to be executed on my pc, so I avoided that, but I would suggest you check, double check and triple check for viruses.
