Game doesn't launch from Riot client Czech

After I click play in the riot client, it doesn't seem to do anything, then redownloads the game for some reason, but then doesn't launch but instead the play button goes back to blue.

In the lutris logs, i found this error:
`(wine:6232): GStreamer-WARNING **: 15:24:24.257: Failed to load plugin '/home/degesz/.local/share/lutris/runners/wine/lutris-GE-Proton8-14-x86_64/lib64/gstreamer-1.0/libgstflac.so': libFLAC.so.8: cannot open shared object file: No such file or directory

I'm running this on Kubuntu, on amd ryzen integrated graphics.

Anyone knows what could be causing this??
