Seems like unblocking driver constantly has issues with trouble finding it.

When i was trying to debug it with one person, we found out it had used incorrect steam path (on linux mint)

it was /home/user/.local/share/Steam/config/steamvr.vrsettings (can't find file, this path doesn't exist)
instead of /home/user/.steam/debian-installation/config/steamvr.vrsettings

This needs fixing, because it affects all steam installations on non-default paths (like debian-based, ubuntu-based)
