What code (project type) are you trying to generate using the tool? Create a new project and try again. Do you see the same issue?

I encountered this error while I was creating a controller and view for a model. Despite trying many times, this error. Of course, creating a different project is not a problem

I'm afraid I cannot locate the problem from this information description. Can you solve this problem by creating a new project?
