the code is

from portablemc.standard import Version
Version().install().run()

the game is installed so is there anyway to run the game without using install()? because when i run the code without internet while the game is installed it passes

Hi! There must be a problem with the launcher's API, I'll look at this for the upcoming patch

[mindstorm38]

Problem found! Should be fixed on next release. Now, if any network error happens while fetching manifest, but the version is already installed, it will work.
