As shown in the image. The buttons may even disappear completely after the window is maximized. After disabling the vertical tab the buttons turn to normal

    Hi,

    This appears to be a bug in this version. You may have already seen another thread reporting the same issue. In this case, it would be best to report it by pressing Alt+Shift+I so the team can look into this and provide a fix on the next update. In the meantime, you can try installing Edge Beta to see if that version works properly.
