ok, that explains it. ESPHome will not partition and flash the spiffs.
that would need to flash via command line: ./device-install.bat -f firmware-filename.bin
that requires esptool install. more info here: Flashing ESP32 devices firmware | Meshtastic
looks like you still have an “old” partition style that is now incompatible with .45+ firmware.
@mc-hamster do you know if the firmware OTA update does re-partition device storage?
