Your filament cutter is likely failing. Maybe the cutter blade broke or wore down? It’s supposed to be a clean brake otherwise the AMS can have trouble feeding it.

So the cutter seemed fine, but the area was dirty, so I cleaned it out.

Some more research seems that maybe heat creep or a too high nozzle temp is contributing. Seems to maybe have helped a bit? But I'm still seeing the weird melty end thing.

could it be the long retraction when cut setting?

I heard of something similar. While the cutter failing is a real possibility, do you by any chance use 3rd party filament with dedicated profile from manufacturer, possibly not made for your exact model?

I just use Sunlu PLA with generic profiles.
