Duplicate of #1735 i think some people in the comments of that issue were able to get it to work using flatseal

The same errror msg comes up like i posted it in the first place. (https://postimg.cc/cKWGryKy)
When I Set "Custom External Player Executable" to "flatpak-spawn", the error msg disappears, but nothing happen.
The external player load not at all.
Maybe it is another bug.
Perhaps some one has a tip for me.
Thank you all :)

Can you zend a screenshot of your external player settings?
