After the update, no game starts

In the previous version of Lutris, all games started. Today updated Lutris and now not a single game starts.
Here is what the console writes when starting the game

Interesting. Maybe try to uninstall lutris and installing again or if the games are on another hard drive or partition, move them or remove a game from lutris and set it up again to test.

The error says it can’t find qdbus. On my machine, that file is located in /usr/bin/ and belongs to qtchooser package (it’s a symlink to qtchooser binary); there also seems to be a qdbus package as well though.

You may want to check if this binary is available first.
