Interfacing (DSI, CSI, I2C, etc.) • i2c just stopped working

I am using a rasp berrypi 5.
I have been using i2c to read external voltage values.
It was working absolutely fine and then just began saying no address found.
I inspected i2c 1 and saw no addresses.

Under /dev the only i2c’s I have listed are 1, 13 and 14.

My immediate assumption was a hardware fault. So I took the same SD card and plugged it into a another raspberry pi, but the issue persisted

I have taken a new SD card, uploaded a new image and still the issue persists.
