Additional Context

If I run claude /ide in an external terminal (i.e. seperate from Rider) running in the same working directory as Rider then Rider is detected and can be connected

I can repro this on Windows 11.

1. Open Rider
2. If I open terminal and run Claude through Rider, /ide is detected
3. If I open standalone pwsh terminal and run Claude with Rider running, /ide does detect Rider running, but is "not in the same workspace" (untrue).

I seem to have the same problem in Rider (2025.2.0.1):

1. The plugin is installed in the IDE (0.1.11-beta) - the icon appeared in the interface
2. The latest version of claude-code is installed (npm install -g @anthropic-ai/claude-code)
3. Initialization in the project is successful, but the status says "IDE plugin not connected"
4. If I run the /ide command inside the Rider terminal, it displays that there are no available IDEs:

5. However, if I run the same command from Windows (CMD or PowerShell), the /ide command is successfully executed and shows the Rider IDE

Update:
Resolved after update Rider to the latest 2025.2.1 version

Update 2:
Not worked after restart OS

I am also experiencing this in the current latest versions of Rider, the plugin and Claude Code.
