I have used 'itemscroller' before and everything is working properly.

I am currently using 'itemscroller fabric 1.20.1-0.20.0', and most of its functions are normal, but only the stored recipe cannot be used.

I tried to change the button, but after clicking it, there was still no response.

I suspect it may be a module conflict issue, but when I only add 'itemscroller', it still cannot be used.

What is the reason for this?

Which crafting inventory are you trying to use it in? You do get the recipe view when you hold A? And you are trying to use the storeRecipe hotkey while hovering over the crafting grid output item? Check that the advanced keybind settings for storeRecipe haven't been changed - does the settings widget have an orange or white outline? If it's orange, then they have been modified from defaults. You can right click it to reset it back to the defaults.
