M2 Mac Mini stopped working with Samsung M8 Monitor

My Mac Mini M2 has all of a sudden stopped connecting to my Samsung M8 Smart Monitor. Up until a few weeks ago it worked fine.

I have tried unplugging everything and plugging it back in in ever order possible.

I have tested the USB C Cable on other devices and it works fine.

I managed to get it to work with my TV through HDMI. Then I was able to tell the mac to connect to the M8 Monitor and it worked. But when I have it just plugged into the M8 Monitor on its own via USB C it won't automatically connect to it.

The Monitor just displays "no signal".

Help Please!
