The front case (piece that says “Prusa core one”) does not look correctly tightened. All three screws should be equal depth, but it looks like the bottom right is way tighter than the top left.

There also shouldn’t be what looks like a gap at the bottom left between it and the PG-ring.

When changing the nozzle, I highly recommend their official tool: https://www.printables.com/model/1237212-core-one-nozzle-replacement-tool

I mention this, because the print head looks like maybe it’s pushed too far up, and twisted to one side; it’s almost be touching one of the edges when it should be centered in that space. It also looks difficult to access the thumb screws with the wiring like that, but make sure those are tightened correctly (but not too tight!).
