I am in the USA. In Windows 11 Home, Version 22H2, start Bambu Studio set both the language for my keyboard and the time zone (why would it do this? How does this help 3D printing?).
At top left there is a pulldown menu (upside down ‘^’) with Preferences; setting Language: English, Login Region: North America seems to have fixed it setting a different language.
A workaround for the time zone is to find the “Set time automatically” setting, and turn it off and on.
