Hi everyone, I found the setting menu is not showing up when I'm doing something like bevel or subdivide, normally there will be a menu setting bevel's edge at that rectangle, but now it's just never poping up.
I am assuming that you accidentally unchecked the Adjust the Last Operation option, which is why your operator menu is not seen.
If you have not unchecked this option then follow Christopherb NBennet`s solution which he posted in the comments section.
In Object Mode, click on the View button as shown in the GIF and then check the Adjust the Last Operation option.
It appears that you are currently running the operation. (as indicated by the dashed line toward your cursor.)
This menu only shows up when an action is completed and it is not visible when the action is in progress.
I would indeed like to see this menu when the action is in progress though, that would be handy. The right-click select forums are the place for feature discussions.
