Error: Failed to probe running application type

[palmitoto]

Hello, I’m reaching out for your help.

I just updated the firmware of my SkyConnect with the firmware nabucasa_skyconnect_zigbee_router_8.0.2.0_115200_sw_flow.gbl from the release v2024.6.2-update5. The process went smoothly, but since then, neither Home Assistant nor Universal Silabs Flasher can communicate with it.
