Question There are sprites that I didn't import

I created a empty unity project.
There are sprites that I didn't import

Please see the attached file
I tried to change the sprite from Sprite renderer.
There are strange sprites like google one in the sprite selection window.

version is 2020.2.43f1
I tried on different versions but it doesn't work

 

When you create a new Unity project, there are a few package-manager packages already installed. You can go to the package manager and uninstall the ones that you are not using.

 

Thanks a lot!
I removed 2D Animation and Version Control Package.
Finally, the sprites that mess me up are gone.
