Modx 3 - Minishop2 making manager blank

Hi. I am trying Modx 3.0.1 locally with Modx 3 compatible Extras and found that Minishop2 is making Manager completely inaccessible.

Fresh install of Modx 3.0.1

Installed Minishop2 and boom!(Could not install package) After refresh, Manager goes blank.
To make manager working again, I have to manually delete the Minishop2 folder from core/components.
Also there are no db tables related to the extra.

Modx version 3.0.1
Minishop2 version 3.0.5
