I have Ubuntu 18.04.2 LTS
Before Patch 9.14, everything was working properly. Shortly after this patch, I had an error message from WINE then League of Legends told me that I had a problem in the instalation and now impossible to launch the client because of a bugsplat. . What I do not understand is that LoL still works on PCs of other people who also use Lutris and who have a PC running Linux. But one person had the same problem as me and we do not know how to fix that.
Thank you for helping us.
