You have two problems.
First keep your nozzle clean at any time. At the start of a print fresh filament is pushed through the nozzle. When this material winds up and touches the nozzle at the side it will bake in and you have a perfect loop. this can catch with your print at any time. Take a pair of tweezers and pull it off right at the beginning. I make sure it winds nicely around the left plate clamp before the print head moves to the print position. Keep this initial filament lump away from your print area.
Second your bed adhesion is poor. Lower the thickness of your first layer in small steps in Cura in advanced settings. If this doesn't help try the glue stick. There are many tips for better bed adhesion in this forum and they vary with the material you use.

Hi and welcome,
It's not easy to see... it looks like your nozzle is a bit to far from the plate, but i'm not sure.
Also what is the filament? It doesn't seem to be an Ultimaker one
