Have you tried lowering the bed temp? Might help with first layer adhesion, in the sense it would reduce shrinking as it cools. Maybe 60, or even 50C.

The defects higher up occur at heights where other features are present around the corner - probably not a coincidence. Your acceleration or junction deviation might be too high - see here: [Snapmaker 2.0 Initial Calibration Settings / Experiences - #27 by untergeek](https://forum.snapmaker.com/t/snapmaker-2-0-initial-calibration-settings-experiences/9928/27)

The gcode file looks fine.
