not sure this is a proper fix but if you change Scrap/addons/config/tutorials.lua line 46 to:
shine = Scrap.Visualizer and Scrap.Visualizer.ParentTab or MainMenuBarBackpackButton,

the addon loads again.

@Jaliborc not sure if this was added by accident or a part of another plugin but searching this addon code Scrap.Visualizer is not anywhere else.

@Jaliborc

Acctually it looks like you have this addon seperated into 3 parts but in this same git. The problem is Scrap.Visualizer get loaded by Scrap_Merchant. For this to work you need to add Scrap_Merchant to OptionalDeps in any toc that uses Scrap_Merchant. This makes the game load Scrap_Merchant

Once this is fixed it does however lead to a different error:
/AddOns/Scrap/addons/merchant/visualizer.lua:6: attempt to index global 'Scrap' (a nil value)

The issue is the ordering of how parts of your addon get loaded. Normally with just one added you would first add in your case mains/main.xml then add merchant/merchant.xml

However parts of your code depend on other parts that are not loaded, you would have to rework your addon code to get this to work properly. Or I guess just go with my other tutorials.lua fix. Not sure Scrap.Visualizer.ParentTab is. If that acctually works or not.
