Can't add pixi interpreter in PyCharm

[hotlogical]

Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

When trying to add the pixi interpreter to a project in PyCharm I follow the instructions and in the "Add Python Interpreter" dialog I choose:

"Select existing"
"Type: Conda"
Path to conda: /home/elc/repos/apitest/.pixi/envs/default/libexec/conda"
"Reload environments"
"Environment: default"

The "default" environment is found but there is a red line around the box containing "default", the "OK" button to finish the dialog is greyed out and the interpreter can't be selected.

Issue description

Unable to select the pixi interpreter in a PyCharm project.
I'm using the latest pixi - 0.40.3
This issue occurs with the latest PyCharm version - 2024.3.1.1
Using the two previous versions of PyCharm - 2024.2.5 and 2024.1.7 the issue is not there and the dialog box correctly selects the pixi interpreter from the project (using the exact same project).

Expected behavior

"Add Python Interpreter" dialog box adds the pixi interpreter to a PyCharm project (and all packages)
