Settings button are not working in JetBrains

[runjinz]

I'm using DevChat version 0.0.9 in IntelliJ IDEA CE, and when I click the Settings button, it doesn't respond.

I found through testing that the button cannot be clicked during generation. I discovered that the following error occurred, causing the plugin to be completely unusable. Restarting multiple times also did not work.

Reinstalling didn't work either, the model list can't be clicked.

Reproduction steps are as follows:

1. Open the configuration, delete the API Key (meaning it is an empty string), and click OK.
2. Go back to the chat window and send Hi
3. Click the settings button
4. No corresponding situation appears
5. Close the IDE
6. When re-entering, all buttons are unclickable.

In addition, through testing, changing the API Key back to "change_me" can restore the initial state.
