The part looks small, so it be doing a lot of short movements at that point and the layers below might not be getting time to cool down right, in Cura you got a setting for min layer time, make this higher and the printer will stop after a layer till the min time in sec is hit that you set, this will give time for the layers below to cool and can help.
This is stringing for sure.
First you can print a "Temp tower" to determine the best printing temperature. A lower value would reduce strining
You can activate retraction
Make sure the cooling fan is set to 100% and they are working fine (no obstruction)
