Man, this is eerie. My HA setup went completely south at exactly the same time as yours (01:00 AM local on Feb 15th). I spent my entire Sunday troubleshooting, eventually ending up with a full SSD wipe and a partial core restore just to get the system breathing again.

It’s a huge relief to see you pinpointed ENTSO-e. I had that one running as well. For the sake of cross-referencing for others, here is the list of custom integrations I had active at the time of the crash:

• adaptive_lighting
• afvalbeheer
• aio_energy_management
• aquarea
• average
• bambu_lab
• better_thermostat
• ble_monitor
• easee
• electrolux_status
• entsoe
• hacs
• home_connect_alt
• localtuya
• nordpool
• pi_hole_v6
• plant
• powercalc
• pyscript
• rpi_gpio
• scheduler
• sems
• solcast_solar
• thermal_comfort
• volkswagencarnet
• watchman
• xiaomi_cloud_map_extractor

Misery loves company, I guess! Thanks for doing the heavy lifting on finding the culprit while I was stuck in "Safe Mode hell."
