seems git clone of v0.3.18 might be the last one using web/index.html which is required here

Because inside tasks.py a git clone is made it takes "latest" but that variant has no longer the web/index.html.
Maybe v 0.3.18 could be used to run it...

Manually adding --branch into clone commands (2 occurrences) seems to fix launcher. Otherwise it's not able to create/import workflows on MacOS. 🔥
