Your i2c bus is stuck, probably because the rtc pulls down the SDA line.

Can you make your machine completely voltage free for a moment? That is
remove any power cords and a maybe existing backup battery.

If you are able to locate the chip on your pcb, there must be 0 V
between pin 4 (VSS) and pin 8 (VDD).
