I had to download YACL for a new version of another mod that didn't require it before (island utils). My game wouldn't launch, giving an error message without any description. I checked mod compatibility for my enitre mods folder and the incompatible mod turned out to be the Pretty hitboxes mod. The game doesn't launch when both mods are installed. I'm not sure whether this is solvable on your part. The mod doesn't have many downloads so it might not be an issue for anyone else, and I found an equivalent mod that is compatible, so the fix isn't necessary for me either, but if you want to include this info somewhere, then here you go.

System & Version Information

• Java Version: Java 17
• Minecraft Version: 1.20.1
• OS: Windows
• CPU: Intel i5-1035G1

A crash log would be very helpful!

I know, but I didn't get one, and there's nothing in the .minecraft folder either
