Event Log - "Unknown Module Type" when loading a project open in PyCharm.

My project has Python code and C code.

When I open it in CLion, I get the following message in the Event Log:

"

Unknown Module Type
Cannot determine module type ("PYTHON_MODULE") for the following module:"orion"
The module will be treated as a Unknown module.

"

In the post https://intellij-support.jetbrains.com/hc/en-us/community/posts/207029775-Event-Log-Unknown-Module-Type, it was recommended to open a new project elsewhere and add my original project as a source folder.

a) Could you give instructions on how to do that in CLion please?

b) I'd humbly suggest better handling of projects with mixed languages opened in multiple JetBrains products simultaneously. The current error message isn't helpful.
