That type of thing often happens with overly enthusiastic pumping (or pumphead removal)
That blue rim tape does look fucked though. Is it not sticky? I've only ever had mine move side to side, not bunch up like that.
It could be, if the rim tape is moving forward and backward it's cut into the valve stem.

... part 2: same happened to the next tube I put in. I have now swapped the rim tape for a tighter version. Scared to put in yet another tube. Seems like the innertube was being dragged around inside the tyre or something?
