!STACK 0
java.lang.NullPointerException: Cannot invoke "com.microsoft.copilot.eclipse.core.lsp.protocol.CopilotModel.getModelName()" because "this.defaultModel" is null
at com.microsoft.copilot.eclipse.ui.chat.services.CopilotModelService.restoreModelName(CopilotModelService.java:293)

Start in CopilotModelService.java at restoreModelName (line 293), reached from the job at line 88. Reproduce the “Fetching model list...” operation with a null defaultModel and inspect the surrounding model-restoration flow. Done means the operation no longer throws this NullPointerException when no default model is available.
