P.S., I don't use lutris nor the staging patches. I currently use nvidia's closed drivers at version 410.78. Perhaps you should try and load steam and see what happens.
In that case I guess you're experiencing bug 45948. Staging has a patch attached to that bug that will allow Steam to log in again.
