Every night, a circular object with a hole in the middle flashes quickly in all colors and stays in place all night long.

For the record, I've lived here all my life and I've never seen or heard of this object before. Now, since I've first spotted it, it's in the sky every night, and it stays in place all night long. It slightly moves from night to night, probably because of the Earth's rotation. The first time I saw the thing, it was around 11:30 pm, and I was walking alone in the street near my house. I saw a weird sphere in the sky that changes colors quickly; from white to purple to blue, to green to yellow to orange to red and so on. I took out my Samsung S22 Ultra and started taking videos and pictures at a high rate with the x100 zoom. In the pictures, the object appears to be circular with a hole in the middle. Since the first sighting, I can see it every night, changing colors quickly in the sky. Since then, I have shown it to multiple people, in person, who were left as confused as me. It can't be a newly placed tower because it's way too far; it can't be a drone because it stays in the same place all night long, the same goes for a plane. It can't be a satellite because of the way the lights are flashing and the colors of them; also, the shape doesn't fit the description of any satellite, the same goes for a planet. For the record, I did check on Skyview and other similar apps, and nothing, including planets, was near the sightings. Overall, I can't understand the shape nor the colors of this weird object that I can see every night now.
