problem
I ran a command to create a new model, but I get the following error and cannot create a model.

The reason I tried the above three is because I thought there was a problem with cloud9 itself.
That's because something is written on the top line of the error.
/home/ubuntu/.rvm/gems/ruby-2.6.3/gems/actiontext-6.0.3/lib/action_text/engine.rb:47:in `block (2 levels) in<class: Engine>': uninitialized constant ActionText :: Engine :: ApplicationController (NameError)There seemed to be an error in the ApplicationController, so I was curious and tried to look into the file.
But I can't open the file. As shown in the image below, the backslash next to the file name continues around.
By convention, only "when opening the application_controller.rb file" is not loaded.
So, I tried the above three to solve the phenomenon that only the application_controller.rb file cannot be opened, but none of them solves the problem. If the file is read properly, I think that the error when creating the model can be eliminated.
If anyone is familiar with this, please help.

Over time, the phenomenon of not being able to open files has not changed.
I couldn't help it, so I created another new environment and started coding again.
As a result, it is working well now.
