If the file paths are longer than 260 characters, Windows may have trouble finding them. Fortunately, Windows 10 added a new feature that enables file paths up to 32767 characters long (give or take).
To enable it, go to the Windows Registry -->
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
On the right side, look for "LongPathsEnabled" (REG_DWORD) and set the value to 1
(I am not sure if you have to reboot, but I'd do it anyway, just to make sure the setting takes effect.)
(If you want to disable the setting, just go back and change the value to 0.)
