My tweakeroo free cam started going light speed. Since then everytime I open mc with tweakeroo it crashes. I'm assumming its beacaues I changed creativeflyingspeed on carpet to 10.

tweakeroo-fabric-1.18.1-0.12.0

What mod version are you using? There was a "light speed" bug in one of the 1.18.1 versions I think, which was fixed in a later release.

The same problem as this guy #325

Even in the 0.12.3 version? Open the config file at .minecraft/config/tweakeroo.json and search for tweakFreeCamera and set it to false if it's currently set to true. If that's not the case, then try renaming the config file (or deleting if you don't care about it) and see if you can then join.

Looks like it was fixed in 0.12.1. So just update to the latest version (currently 0.12.3) and see if it's fixed.

It still freezes on joining world screen.

Free Camera should get disabled every time you leave a world though. Does it still freeze if you move out Tweakeroo from the mods folder? In that case it would be something else. Did your player somehow get zoomed into some far distance?

Everytime I add tweakeroo to mods folder mc freezes on joining world screen. And yes when I press p ( my shortcut key for freecam) and pressed W it went 10000000000 blocks away.

Yes, now it works. Thank you so much.
