That doesn’t look like the rotation of the earth to me, but more like you bumped the camera during the exposure. Does this camera have some sort of internal stabilizer that might have still been adjusting when you started the exposure?
If you notice the stars in your picture, it’s like they have a weaker tail where as earths rotation would cause it to appear a single line, see this example https://p.drkt.eu/2023/_MG_4474.jpg
