Can't remove Windows 10 from my mac. Mac doesn't work like it was before installing Windows

Hi,

I've got a problem with deleting Windows partition from my Macbook Pro 13 (2017) (Monterey).

After I installed Windows 10 with Bootcamp Assistant I can't use finder search bar and spotlight also doesn't show me any files I have in finder. I've tried adding Macintosh HD to spotlight privacy tab but it shows me that I can't do it. Also I can't delete Windows with Bootcamp because it just shows me a loading bar. When I open Disk Utilities there is no Bootcamp on a left side and in Startup Disk (in system preferences) there is nothing, just loading circle.

Can anybody please help me remove windows from my macbook and help me to get it work correctly?

Thanks in advance
