Can't launch anything on Lutris

Support

Hi
I recently updated some packages and now i can’t launch anything on Lutris.
This is the error Lutris gives me:

Traceback (most recent call last):
  File "/usr/share/lutris/bin/lutris-wrapper", line 16, in <module>
    from lutris.util.log import logger
  File "/usr/lib/python3.7/site-packages/lutris/util/log.py", line 9, in <module>

    _w_long = _bootstrap_external._w_long
AttributeError: module 'importlib._bootstrap_external' has no attribute '_w_long'

I reinstalled python and lutris but nothing has changed.
The distro i use is Gentoo.

Probably has to do with multiple versions of Python being installed. Probably 3.7 next to 3.8.

See this stackoverflow post:

I removed python 3.8 and fixed the error, but i still can’t launch anything.
I also launched Lutris in debug mode, seems that every game stops with code 6.
Here’s the dump: https://paste.ubuntu.com/p/dFrxkrhVbG/

The only thing which looks interesting is the first part:

Yea, that’s the old GPUs i use for folding@home.
I took them off from the rig, but that didn’t solve the problem.
EDIT:
Also i got this now:

Fatal Python error: Py_Initialize: can't initialize sys standard streams
Traceback (most recent call last):
  File "/usr/lib/python3.7/_bootlocale.py", line 35, in getpreferredencoding
    if sys.flags.utf8_mode:

Looks like error in python.Have you tried reinstalling it?

Possibly you have an older version of python enabled which is different to the version of python that lutris is now installed for. Try running:
eselect python list
and if you see something like the following

  [1]   python3.6
  [2]   python2.7
  [3]   python3.8 (fallback)
  [4]   python3.7 (fallback)

Then it means that python 3.6 is the default python3 installation, while lutris was installed against python 3.7 based on the output you’ve displayed. You just need to run eselect python set 4 to switch to python 3.7 or adjust your use flags for lutris to set python_targets_python3_<n>, where <n> is set to the minor number of what every version of python3 you have enabled as the default to ensure lutris is running against the system default python.
