I am unable to open gradlew-jar.bat.
I checked the GitHub repository and looked into similar support cases, but haven’t made any significant progress.
The image shows JDK 17, but I’ve tried all versions from 17 to 26.
With versions other than 17, an error appears immediately after startup.
I’ve spent over 12 hours today trying to pinpoint the cause of this issue, but I’ve hit a dead end.
Please guide this lost sheep.
I’m completely exhausted, so I’m going to sleep and wait for a flash of inspiration.
I’m not very good at English, so I’m using a translation tool.

I tried JDK 21 again, but it still doesn't work.
I'm so exhausted I can't think straight, so I'm going to rest as much as possible.

Looks like it’s finally done.
It seemed like several environment variables were interfering, so I deleted them, restarted the system, and then completely forgot about it.
Can you believe such a dumb thing happened?????
Thank you so much, you’re so kind.

It looks like all the issues have been resolved.
I can enter the world, and XXMI is loading properly 🙂
However, I can't find the text box.
How do I use the commands?
I'll look into it.
It was a beginner's mistake, but thank you so much.

You cannot use the command through the in-game chat yet because the proto related to chat for LunaGC6.5 is not fixed yet.
However, you can still type the command in the LunaGC console/CMD.
