This is because the temperature drops quickly,
we recommend you slowly cooling the camera to solve the problem:

Before letting it cool down to target cooling temp, please keep it at 5℃ for 2-5 minutes, then cool it down to target temp and if this continues to appear, it will basically disappear in 5-6 minutes.
You can also refer to this guide to redry the disccants.
