At no point means means whenever - at boot, when locked, when screen saver is engaged, whenever.
Thanks for confirming that you don't see it on lock. The steps I would take now are (in this order)...

sfc/ scannow
Run SFC Command in Windows 10

Dism /Online /Cleanup-Image /RestoreHealth
Use DISM to Repair Windows 10 Image
(you may need to repeat these two steps up to 3 times until no errors are found)

If the above steps don't fix it, then an in-place repair install almost certainly will (you will be able to keep your installed apps and files).
