Venus OS V3.90 beta1-5: VRM reports that it has lost contact

With Venus OS 3.90 beta1 through beta5, real-time power data and Remote Console still work, but VRM reports that it has lost contact with my Cerbo GX. Voltage, current and other values are no longer updated correctly.

After downgrading to 3.80, all values are transmitted again and VRM shows the connection as restored.

This is reproducible when switching between 3.90 beta and 3.80.

Thanks for the report.

No extra modifications or large image. Build-in Shelly interface and SMA pv inverter data sources are in use.
