It's the same underlying issue as the other one. The STM32 isn't outputting the spikes, it's an artifact of how you're measuring.
Probably wise to reduce GPIO speed to mask some of the effect.

You disconnect something ... Too maybe you need learn I=U/R (pin can drive only limited current)
Normal PWM use RC not LC .
