Crash on playing iris profile after install

I followed several install guides for iris 1.20.4 that all say the same thing.

  • Make sure Java is up to date
  • Download the Iris installer from the website
  • Make sure minecraft is installed and load 1.20.4 to main menu, then close game and launcher
  • Run Iris installer jar file with java, select 1.20.4 in the dropdown, click install and close when complete
  • Play minecraft using the new Iris profile
Despite redoing all of this at least 5 times I cant escape this error and I dont know why, I've tried moving installation directory but then it fails to create the iris-reserved directory, when i create the folders manually it launches minecraft fine but it does not include the jar files within the folders so launches minecraft without Iris.
If i copy the jar files into the manually created folders I get the same error as I did at first.
The error log should be included in this message.
