I experiment like 6 hours for a alternative solution, cause old one doesnt work
How to fix this bug currently (updated):

1 Download Optifine "https://optifine.net/adloadx?f=preview_OptiFine_1.12.2_HD_U_G6_pre1.jar" and download it
2 Download Sound-Physics from "https://github.com/djpadbit/Sound-Physics/releases/download/1.0.10/Sound-Physics-1.12.2-1.0.10.jar" and put both in the mods folder of the modpack
3 Go into the config folder then mod-director folder and delete only the optifine.url.json file inside
4 Launch the modpack and it should open fully

The linked datas are from the "mod-director" folder, if u open the two .json datas of optifine and sound-physics with editor u can copy the URL links and download the 2 mods

i deleted both and it worked
