That's strange, could you please share your project folder Structure and also the IWeth file? Did you named differently and uses WethInterface instead right?

I tried a bunch of random stuff and it worked suddenly haha, i think the contract name was the issue!

Just an idea: Can you check if the address of the contract is listed under
build > contracts > deployments > [some network id]

If it is deployed there, the network ID should match the network you are running your code with
if your command line looks like
brownie run ./scripts/deploy.py --network rinkeby
then the path should be
build > contracts > deployments > 4> {contract address mentioned in the error message}

This was proper, i checked it. Thanks for the reply!
