please fill out the issue template properly. I can't tell what your problem is without more information
needed info: minecraft version, mod version

actually on closer look; this appears to be a duplicate of pinned issue.
Update to baritone version 1.8.3 and please check for duplicates before posting issues.

thankyou very very much
