Solution 1:[1]

I ran into the same issue a few days ago. I changed the name of the interface file from "IWeth.sol" to "WethInterface.sol".

I don't know why it worked, but you can give it a try.

Solution 2:[2]

you can name the file what you want but, when you want to call the interface you need to call the name of the contract exactly per example

contract WethInterface {}

wethContract = interface.WethInterface(wethAddress)
