This is definitely a bug that we'd like to investigate. So please do the following:
- go to Help | Debug Log Settings
- add #com.jetbrains.cidr.execution.debugger there
- collect debug logs while starting a session, logs can be found in Help | Show Log in <File Manager>
- send logs to us via submitting a request here and attaching log files.
Update: If you have a timeout problem, you can also try and increase the timeout value.
