It seems that wslpath -w (current path) is executed on the Fedora Remix side every time a command is executed.

wslpath -w /home succeeds on Windows 11, but becomes error on Windows Server 2019.

It looks like the version of WSL that you have in Windows Server 2019 is ancient. It corresponds to "Windows 10 version 1809". At that version you couldn't access the WSL filesystem from Windows thus wslpath is telling you that.

For example if you execute wslpath 'C:\' probably it will answer with /mnt/c
