The texture pack broke because it does not show up and there was an error that the game could not get pack info.
Dang. Well, It hasn't been updated for quite a while. I'll look into it. What version were you using? If it was a 1.17 snapshot, that may be why its not showing up.
I opened 1.15.2 and 1.16.4 (in OptiFine), maybe the trouble was Optifine
