Hello @Ugijago, noted at https://github.com/ValveSoftware/steam-for-linux/blob/master/RelNotes.md#installation, sharing a Steam Library folder between OSes is not supported and might lead to undefined behavior.
This is a rather extreme example, but not a Proton bug. It might be an issue somewhere in the NTFS kernel module used by your distro and would need to be investigated on the kernel side.
Closing as not a Proton issue.
Nothing extracted yet.
