My thermostat stops cooling after a minute or so, the it starts a count down “Starts in x:x min”, about 3min and starts again for a minute.  The heating works fine. Image of the wires is attached

One thing is for sure, you need to trim all those bare copper wires. The wires should be straight and inserted fully. Now the problem are experiencing is most typically associated with a low battery voltage.

Thank you! I moved the green wire from G to C and it appears to work now. The green wire was connected to G at the furnace.

Sorry I meant to say the green wire was connected to C at the furnace

At the furnace you need to move the G wire to the C terminal if you are going to use that wire for Common and not Fan.
