unable to open UE5 project on SSHFS share

Im probably missing something in my SSHFS config, but i thought i’d try asking here first.

I’ve got an SSHFS share set up on a server, and have it mounted in windows thanks to sshfs-win and winFSP. It works as i would expect for most things, but im unable to open an unreal engine project stored on it. I can create new projects on it, but cannot open them.

If I attempt to open a project I get a crash stating that the intermediate directory could not be created.

This suggests a permissions issue, but I dont believe that to be the case given projects are created without issue.
