So what I see here is:
- target temperatures are 205 and 65 degrees
- the firmware says something about a print timer being stopped
- after that the target temperatures are 0
Looks to me like this firmware has some idle temperature off functionality and you are missing something in your slicer's or OctoPrint's start GCODE script to tell your printer's firmware that you are in fact printing via serial.
I cannot tell you what that is however, I don't know what firmware you have running there. If it's Creality stock firmware, reflash standard Marlin, these forums are littered with issues with Creality firmware.
