'Create new binding class' does nothing

[robbaman]

When attempting to add a new binding class from a feature file the dialog to enter the new file name does not appear. Instead the log contains the following error with stacktrace

idea.log

I'm running the following versions

Do you see any error in the Rider Logs ? In the file backend.log

[robbaman]

Not in the backend, but in the idea.log file there is an error (see attached file for more)

This happened to me, and I noticed there was a hidden SpecFlow import in the project.
It was coming from the implicit usings, and even after removing it, the error persisted.
Then I realized there was also a SpecFlow include in the .csproj file

[robbaman]

Thanks for your reply. For me this doesn't seem to be the case. There is no (transient) reference to any reference named Specflow in my project. A quick search in the project.assets.json file only yielded one result when searching for Specflow is the licence file SpecFlow.Internal.Json-LICENSE-MIT.txt as included in Reqnroll v2.4.1 and Reqnroll.Tools.MsBuild.Generation v2.4.1
