URL error

Hello,

My website was set in my wordpress admin as https://maskin.lu
I tried to change it to https://www.maskin.lu.

I, unfortunately, entered a spelling mistake and saved the website as https://wwwm.askin.lu

Now I can not login and do not know how to change the settings.

Can someone help me please?
