Unable to install games with Lutris

I can't install any GOG games with Lutris. When trying to install any game it shows a popup with "Failed to retrieve wine (None) information" and then nothing happens.

It did work flawless before, when I tried it for the first time like 2 weeks ago. But now it gives this error on every game I try to install. For testing purposes I tried to run the already installed game and it worked normal. Then I uninstalled it, and now it has the same error when I try to install it, so it seems to be no game specific problem.

I didn't change anything in Lutris afaik, didn't even open it since my first test 2 weeks ago.
