First later problem

Attachment 17508Hey guys so I’m having a first layer issue that I’m not understanding how to fix. Saturday my ender 3 worked just fine, printed the new dragon from flexi factory but now today I can’t get it to even print a proper first layer (see pic) I’ve tried several .stls and different slicers. I’ve tried releveling the bed, checked for any clogs, changed filaments, cleaned the bed(glass) and tried using a layer of glue stick but nothing changed. Anyone know what might be happening? I wonder if it’s a nozzle issue
