Lutris unable to launch

Hi everyone

All was going well with some games running and lutris being fine, but after manually adding a game and then a strange system crash, I am no longer able to launch lutris.

Here is what I get when running from command line (-d produces the same output):

  xxxusr@X-Laptop:~/lutris/bin$ lutris
Traceback (most recent call last):
  File "/usr/bin/lutris", line 29, in <module>
    from lutris.gui.application import Application
  File "/usr/lib/python3/dist-packages/lutris/gui/", line 30, in <module>
    from lutris import pga
  File "/usr/lib/python3/dist-packages/lutris/", line 10, in <module>
    from lutris import settings
  File "/usr/lib/python3/dist-packages/lutris/", line 28, in <module>
    sio = SettingsIO(CONFIG_FILE)
  File "/usr/lib/python3/dist-packages/lutris/util/", line 11, in __init__[self.config_file])
  File "/usr/lib/python3.5/", line 696, in read
    self._read(fp, filename)
  File "/usr/lib/python3.5/", line 1012, in _read
    for lineno, line in enumerate(fp, start=1):
  File "/usr/lib/python3.5/", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf3 in position 1: invalid continuation byte

Running Ubuntu (Gnome) 17.04, have tried:

apt-get remove lutris
apt-get purge lutris
apt-get remove python3 (this may have been a mistake!!!, did reinstall after)

and then multiple reinstalls of lutris.

pgrep doesn’t show lutris as running in the background or anything.

Any help much appreciated!
