Is View > Extras on?
Please post a screenshot.
Definitely check if Extras is on, I agree.
Also under Show most are grayed out however
Layer Edges (Ticked)
Grid (not ticked)
Smart Guides (Ticked)
Pixel Grid (Ticked)
UV Overlay (Ticked)
All (Not Ticked)
None (Not Ticked)
It does not seem to make any difference if grid is on or not as the handles are not available.
I have reset the preferences and it works now.
I used To restore preferences quickly using a keyboard shortcut: Press and hold Alt+Control+Shift (Windows) as you startPhotoshop. You are prompted to delete the current settings. The new preferencesfiles are created the next time you start Photoshop.
