1.20.4 DH not working

Hello! I am using the DH from the #links-n-downloads nightly build version for 1.20.4, however I don't see any change in the chunks loaded. "Enable Rendering" is set to True

I get no errors but I see a weird line appearing (in the image provided)

I run no other mods for fabric, only DH
Is there anything I could have missed?

Thanks!
