Lutris doesn't open, unable to load locale dir

So I just installed Lutris (through the included software manager), but the application just doesn’t open. When started in the terminal it doesn’t do anything either and says
“Unable to load locale dir, translations won’t work.
Your version of python-magic is too old.”

Does anyone know how I can get it to run?

Update: After a few restarts it just worked.

Solved (just restarted my pc 2 times)

That’s because there isn’t one. That’s only an informational message.

Nothing to see here
