Windows cannot find 'C:\users (insert file directory)' make sure you've typed the name correctly.

Since the latest Windows 10 update I've been unable to open anything in 'my pictures' folder with a double click. I get the following error message every time I attempt to open a picture file or video file: Windows cannot find 'C:\users (insert file
directory)' make sure you've typed the name correctly.

• I've looked at my folder's options and 'quick access' is not set.
• I can open the files by right clicking and selecting 'open with'.
• I've found no issues after running 'sfc /scannow'.

Please help!

Thanks.
