    Hi @sns ,

    Open the subsite in SharePoint designer to find the default.aspx.

    If the default page has been locked or checked out, please check in or discard check out it:

    Hi @sns ,

    From your screenshoot, the web part is a calendar list, in list, there is no Check in/Check out.

    Please append ?contents=1 at the web part page url to check if you can delete the dedicated web part.

    As a workaround, we could also close the web part in web part mainentance page:

    Hi @sns ,

    Sorry to confuse you!

    I could reproduce your issue if the page has been checked out:

    Please go to the page library which store the web part page, find the user who check out the page:

    Then discard check out or check in the page, refresh the page, delete the web part again to comapre the result.
