@AntonioCarta just curious, why don’t you use WSL on Windows?

I usually do. avalanche’s dependencies should support Windows, so I expected everything to work fine in this case. I guess at this stage of the development we can ignore Windows bugs if we explictly say that we do not support it.

Yes, we should aim to support well windows only for Avalanche official release v1.0, I believe!
