I have been absolutely losing my mind. I have been trying to make a forge 1.12.2 server which I have done in the past and succeeded without a hitch not only in 1.12.2 but in 1.8, 1.16, and 1.14. The problem is, this time I get this error:

Every single time. I've seen posts saying uninstall all java installations and download JRE 8. Well, I did that and nothing has changed. I then saw a post saying to fix my config file which I did. It did not work. After that, I completely deleted Minecraft itself and redownloaded it in the hope to remedy the problem (as well as restarted my computer many times throughout all these processes). Nothing. All this happened while my 1.17 hardcore vanilla server ran with 0 issues. I've run into a wall and can't find nor think of anything else to try. Can anyone help fix this?
