Malfunction and loss of power after starting (1.4tsi)

[caddymaximal]

caddy maxi 1.4tsi 2019. The outside temperature was 0 C. I started the car, after turning in 1st gear, the car suddenly did not react to the gas, the power was lost. In 1st gear, the car drove very quietly. pressing the gas did not scream the car. When I stopped the car, the rpm varied strangely. I turned off and on again and everything worked as before. Anyone have experience with a similar model and event?
