Cannot open files on very long paths.

This has been reported multiple times on the videolan forum, see here for a thread: https://forum.videolan.org/viewtopic.php?f=14&t=148760&p=500730#p500730

I can confirm that I have encountered this bug multiple times and it still exists in 3.0.8 on Windows 10 as of today.

I have optimistically assigned the "component" as Input: file system, but I'm not sure if that's the right place.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
