I cannot debug with RubyMine since your last build

Hello,

Now I get this error when trying to start the app in debug mode

Error running 'Development: XXXXX': Rails server launcher '/home/franz/Projects/XXXXX/bin/rails' was not found in a project

I have 't changed anything in my project and yet I can't debug since this morning
I use ruby 2.2.10 and Rails 3.2.22.5
"rails s" in the console works perfectly
The menu "Run / Debug 'Development: XXXXX" fails with the above message, I don't know what is the whole command being run, it's not displayed by RubyMine
I use rvm but everything is the same as for the past 2 years
RubyMine about window says : Build #RM-221.5080.196, built on April 11, 202

Please help
