Does the error also occur with new versions? Also, can you try running with Java 17 instead of 18?

The answer is yes to both questions. I tried with Forge 1.19.2 (failed at the same part) and I've uninstalled JDK 18, installed JDK 17 (checked java version on cmd typing "java -version") and also crashes

PD: I've also tried with JDK 19 and still crashes

In order to root out one of the more common issues, we'll need to see your hosts file. Here's the steps to getting this file.

1) Press the Win + R key on your keyboard.

2) Paste the following into the prompt that opens: 'notepad %windir%\system32\drivers\etc\hosts'

3) Use Ctrl+A to select everything in the file, then Ctrl+C into the textbox to post to this thread.
