Check if bootstrap and loadup is finished?

Hey I currently have the problem, using the tk-blender toolkit, that when I try to import the sgtk module in a Blender Addon it just crashes. And I assume it’s because sgtk is not properly loaded yet or the bootstrap process is not done. If I import the sgtk module in the function of my Blender Add-On in which I use it, everything works as expected.

My question is can I somehow check when the bootrsrap process is done and only then start import the sgtk module?

Not sure about how exactly Blender and the integration works but would it not be possible to create a SG app for your blender functionality?

Thats the official way of adding app/plugin functionality to software in SG Toolkit.
