I’m using Isaac sim 4.5 version. Suddenly, the Windows > Extensions doesn’t function. When I try to open Extensions tab, the Isaac sim crashes (Isaac Sim is not responding).
- Other tools like, VS code extension, Robotics examples, under the windows function properly. The issue is only with extensions.
- While opening the Isaac Sim application, the Isaac sim opens without any issue, but there are few warning messages which I haven’t seen earlier. The warning message is as follows:

- Someone posted this issue earlier and suggested to try opening isaac sim after deleting .toml files inside the config folder. Didn’t work for me.
- Also tried reinstalling the Isaac Sim multiple times, but it didn’t work.
