Thank you for notifying me. We have immediately disabled adfocus after confirming they were compromised and apologise if anyone ended up running the exe contained within. I recommend running a virus scan if you did run the exe. Forge doesn't distribute any exe files when downloading modern jar installers. https://support.microsoft.com/en-us/windows/help-protect-my-pc-with-microsoft-defender-offline-9306d528-64bf-4668-5b80-ff533f183d6c The download pages are now safe again.

Rule 3 - please do not dump the log into the thread directly as it becomes hard to read. Share a link to your log on a paste site like pastebin.com

Please share a new debug.log running Java 17

To fix the issue, you need to turn off your ad blocker when visiting the Forge files site and when on adfocus.

1.20.1 needs Java 17. You're using 18

We need more info. Please share a link to your debug.log and crash report on pastebin.com. Instructions on how to do this are in the FAQ.

GPU, but you should do both anyway as MC is also CPU-heavy. The fix is to update it. You shouldn't downgrade as you're already on a driver version that's over a year old for this issue to occur and has long been fixed. Downgrading further will cause stability issues and significant performance drops. There are no plans to workaround the issue in Forge as people are encouraged to upgrade away from a known old buggy driver. Make a system restore point just in case, then follow the guide in the FAQ.

Read the FAQ. It tells you how to get the debug.log
