yeah just try remove them to another folder and if it work then we know there are a package conflict, and then you can try add the package again one by one until you find which one there give trouble…i know Bakery gives a lot of conflict if you have that one installed…
I think the best place is this forum here, but there are a lot of videos out there , i like @GavinCrump videos and @jacob.small and @solamour office hour on youtube and many other…or just practice so much you can 
and read so much post here as possible

Perhaps with the package of the first node you showed us?
no worry it isnt a conflict, just say ok, more an information i guess
Copy the contents of the custom node out to your graph workspace and connect the inputs to it. That will give you any errors that the custom node is having.
