CerboGX 3.50~18: batteryaggregate alternates between found / disappeared

Victron CerboGX 3.50~18
2x Renogy 100AH batteries, parallel
Victron SmartShunt 500a
Victron SmartSolar 100/50 12/24v

Since upgrading to 3.50~18, the batteryaggregate is in a constant state of appearing/disappearing every few seconds, and never shows valid data.

Contact the provider of the battery aggregate software via their github or other channel as they need to update their software to work with Venus OS as it upgrades.
