This is because C:\Users\wucha\AppData\Roaming\Python\Python310\Scripts is not on the environment variable PATH. You will have to add it, that's out of pip control.

Defaulting to user installation because normal site-packages is not writeable

That's another issue, out of pip control.

I think you're not asking in the right place.

Again, this is not a bug. You only can't access to your system site-packages, so pip will install your packages into your user site-packages. Also, how did you install Python?

Anyway, this is not a pip bug. You may want to ask in a help forum, or mybe in the Python Discord.
