Dirty build plate. Greasy spots causes the filament to not stick. Use a spray of soapy water and a microfibre cloth to clean it. Just water and dish soap works amazing for degreasing. No need to use isopropyl alcohol. Nozzle height looks okay on the front left I think. Maybe a tad too close, but shouldn’t be a problem. On the back it’s way too high. Make sure your bed leveling is a bit better

This is my guess too. I clean mine with soap and water and rince it in the sink. Like my dishes.
