Upgrade issue?

[chrisgla]

Hi,

Quite a new install, upgraded to latest and now get dark screen with barely visible server 500 error on rates and pv graphs, couple of log examples below.
Could well be something I've not configured correctly yet but was working yesterday.

System: Home Assistant OS 16.2 (amd64 / qemux86-64)
Home Assistant Core: 2025.9.4
Home Assistant Supervisor: 2025.09.0
