Junie doesn't work on pycharm 2026.* on macOS x86

After updating pycharm to any version of 2026, it is impossible to send a message in the junie window. The plugin is installed, updated to the latest version, the plug-in window opens, you can enter a message in the window, you can select options, you can't send a message. You also can't open the pldagin settings.

Start by reproducing the issue on PyCharm 2026.* running on macOS x86, checking both message sending in the Junie window and opening plugin settings. The issue provides no files or tests, so first gather the relevant plugin diagnostics and identify the affected entry points. Done means messages can be sent and plugin settings can be opened normally.
