IntellJ Plugin Copilot Agent crashes on startup

Bug

Body

I'm running Intellij 2024.3 on Linux, and the copilot plugin has stoped working. Uninstalling / reinstalling as no effect. It claims it can't login to github, but if I go into the plug in settings and click on "Github Copilot account settings" it takes me right to my account. Also the github plugin is working fine and logged in.

The agent fails on startup 100% of the time. Here are the logs:

Any answers here? My copilot on Mac is doing the same. I've uninstalled the Intellij IDE, completely wiped ALL files and directories created by the IDE, removed all settings and caches. I've downloaded the latest version of Intellij, and I've reinstalled the latest copilot plugin. I've removed any version of Java from my system. I have the same proxy settings in intellij set that are set in vscode:
