The fl in VS2026 cannot be used in copilot!

Whatever I filled in the API Key,It tells me "Can't add modles"

Too add, in VScode ,I was told " Unable to call the Phi-4-mini-instruct-generic-gpu:5 inference endpoint due to 500. Please check if the input or configuration is correct. Refer to the Output Panel for more details. "when I try to use github copilot as well.....😭
