Thanks for reporting this @fredmo.

This is probably due to the namespacing difference between elevated and non-elevated WSL. Can you try to mount the folder inside /mnt/wsl ? This folder is shared between all namespaces.

I confirm if the mount is done on /mnt/XXX , it s working correctly. Explorer sees the content of the sshfs mount.
The issue is present when the mount is on : /mnt/user/XXX

In fact, I reproduced
if the sshfs mount is done in root , Explorer works.
if the sshfs mount is no root, Explorer fails : chown user /mnt/test , sshfs XXX /mnt/test , Explorer has the same popup.
