Isaac Sim Extension Generator does not work

Isaac Sim Version 4.1.0

I tried to build an extension using the Template Generator. I managed to follow the very first steps of the tutorial and it generated the folders Docs, Config, Data and Name_of_extension_python where i wanted them to be (in folder main_folder/my_extension)
When opening the extension manager Isaac Sim just does not react anymore and i get the following error/warning in the console:

[ext: .thumbs] Extensions config ‘extension.toml’ doesn’t exist at error_path or error_path/config

the two given paths don’t have anything to do with the extension i created although they are stored in the same main folder like this:

main folder

  • error_path
  • my_extension

i might have tried to build an extension under error_path earlier so that warning might come from an earlier attempt but i dont remember very well.

Also, i already tried reinistalling isaac sim, but i still get the same result of the mentioned warning and the nonreactive state of Isaac sim when trying to open the extension manager.

My idea was that the warning comes from an old attempt of creating an extension under error_path, that i deleted, but that is still referenced somewhere.

Can someone help?
