I got this output

Does it have anything to do with when I added local ganache to the network list ?
with brownie networks add Ethereum ganache-local host=http://127.0.0.1:7545 chainid=5777
If yes how i can remove ganache-local from the network list to re add it.

Yes the error is saying you have not added the host correctly, try removing and adding the network again with:

• brownie networks delete ganache-local
• Then try adding it again, be sure to not have any typo
