Without looking at any of your data, I will pretty much guarantee you depleted the necessary volts needed to fly. Example, lets say the battery has 14 volts fully charged. And lets say the Mavic requires a minimum of 11 volts to function. Now, when you go full throttle Forward or full throttle Upward for a length of time it will eventually drop below the needed 11 volts. Should you be at full throttle on both Forward and Upward at the same time, the volts will drop rapidly.
Depending on how charged up the battery is at start up will determine how soon you might reach that say 11 volts point. Cold weather is another huge factor in this situation.
Somebody else will need to chime in and let us know what the volt drop off amount is on the Mavic. This is why I kept referring to the word "say". I'm pretty sure it is 11.0 volts, but I'm not a 100% sure. Btw, I need to point out that this issue is actually based on the amount of volts in each battery cell. With the numbers I gave above such as 11.0 volts, would mean the cutoff pint for each battery cell would be 3.66 volts. Even though my numbers might be off you should be able to get the idea about limited volts.
At this point the only other thing to mention is about return volts. When you are say full throttle and drawing a lot of current, as mentioned the volts are dropping. But if you bring the throttle sticks back some to say 70-80% the volts will usually become steady and not drop. The GO4 app has a option to display live volts in the upper right corner of the flight screen. It will change colors based on the amount of usable volts. It goes from green, to yellow, to orange, to red. You should make a habit of monitoring the volts display and never allow it to reach the red color. Remember to let off some will allow the Volts to Return to a safe level.
