The error code is a bit different this time but it should be the same case.
Your system seems to have CSIDL_PERSONAL / My Documents pointing to an invalid path.
A brief Google surfaces the following: System call to get the 'My Documents' folder failed | Legacy Family Tree
For Windows 10 maybe try https://www.tenforums.com/tutorials/23504-restore-default-location-personal-folders-windows-10-a.html
Alternatively, to ignore this error, start Anki with -b option.
"C:\Program Files\Anki\anki.exe" -b "%APPDATA%\Anki2"
