All it says is 'temperature sensor error', nothing to say which sensor it is talking about. The fans are normally off on the first layer, 50% on layer 2, then 100% beyond that.
The bed and nozzle are heating up for certain and pretty close to what they should be.
A loose connector seems the obvious cause but can't explain why only on the first layer. I am assuming that if the controller sees an open circuit on a sensor it halts immediately.
Does the nozzle sensor have a connector around the hot end area?
What does the temp error actually say? Knowing if it's nozzle or bed could narrow it down a bit.
Do you have fans come on during the first layer?
Could be a loose connection.
