Not able to drag in assets from Isaac Assets after the startup hang fix

[SuomiKP31]

After commit 7e80e14f45fff853342f43e4a25713c18d3aa076, using this extension seems to cause Isaac Assets to not work correctly. I noticed that the version of Isaac Sim has been changed to 2023.1.1a while I'm on the release version 2023.1.1. I suppose the issue will be fixed in next major release?

I got this error message:

Restarting Isaac Sim does not resolve this issue, even if the OIGE plugin is not loaded.

Loading directly from content server still works, for example:

def create_test_env():
    if World.instance():
        World.instance().clear_instance()
    world=World()
    world.scene.add_default_ground_plane(z_position=-1.0)
    # Load "Ant" from Isaac Assets
    # usd_path = "http://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/2023.1.1/Isaac/Robots/Ant/ant.usd"
    # prim_path = "/World/ant"
    usd_path = "http://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/2023.1.1/Isaac/Robots/Humanoid/humanoid.usd"
    prim_path = "/World/humanoid"
    stage_utils.add_reference_to_stage(usd_path, prim_path)

This will load one humanoid into the scene, however still cause the entire app to freeze for about 2 minutes, like before the aforementioned commit. What is the root cause of this content server related hang?

when I drag a sensor into stage , I also meet this issue , have you solve this problem? thx

Basically any playload will break. No solutions yet, but you can use the script editor to load the prim manually, as a workaround. I've had the code snippet in the issue but I think things still need to be fixed on NVidia side.
