Hi, your mod seems to be incompatible with Double Slabs, it just crashes on startup.

alloyed-1.16.5-v0.3a
DoubleSlabs-1.16-3.7.3
Forge 36.2.34
Minecraft 1.16.5

My computer:
AMD Ryzen 3 3200G with Radeon Vega Graphics 3.60 GHz
8.00 GB (usable: 5.95 GB)
Windows 11 Pro 22H2

I believe this was fixed for create as a whole in subsequent versions. I myself made an initial report for it around that time on the create page, I would look there instead. Alloyed may be interacting with create to do something between the two mods and they conflict, causing an error.
