You can't

Can't really help with a pirated launcher

You didn't put a space after -jar

Use .scale set or ctrl + scroll in the menu

Yes, you can dm me with your old and new username

oh i see, yeah it works now thanks 🙂

and can u tell me how i bypass the fly antycheat?

I believe this is resolved on 1.21 and above with iris

It was basically like BlockESP except it would highlight things that it determined to be bases or had base-like structure, but it was mostly inaccurate. Either xray, blockesp or tracers would be better for finding bases

Looks like a cracked launcher, but it's most likely an issue with a mod you have.

Fixed, found a old post from a couple years ago (took me a couple hours to find) re installed the donor installer and it fixed it.
Thanks for the initial help ❤

@Dyiing I tested it now I joined into another player alt acc and see derp thank you so much bro! And you have best client guys by my opinion.

AFAIK, (for now) we can't get it here. Looked everywhere for it already 😅

Are you on MP or SP?

If you are on MP note the following statement from @Dyiing
"FastBreak has never been able to instantly break blocks, unless you are on Singleplayer. On Multiplayer it's simply too fast for the client-to-server connection."
