2016 camaro not starting

When I go to start the car it it says “press clutch to start car” and will only go into accessory mode and I have the clutch compressed. But I will leave it for a few days and then it will start to work again. When it start it has started to occasionally have a light for service stabilitrack and I will loose all my electrical gauges.

I have also replaced the clutch position sensor and have the same issue
