If the two mod are present (Headed amd GeckoLib), a crash will occur if you try to type "bee" in the creative gui menu
I report the issue here: Pedro270707/headed#4

Fabric 1.19.4 - 0.14.9
Latest version of both (Headed amd GeckoLib)

Provide an error with just those two mods present and we'll have a look

As it stands, anything could be coming in the way
