[MAC][CLIENT] LOL Client launch and stop immediately

when i launch league of legends on my mac, i see the "Riot Games" overlay (big white letters) but then nothing happens.

This is what i get in my log files when i launch the client:

000000.000| ALWAYS| Logging started at 2019-10-23T21:37:11.000 000000.001| OKAY| Running in Standard Mode from cwd '/Applications/League of Legends.app/Contents/LoL'. 000000.001| ALWAYS| Application Version:9.21.294.813 - CL:2940813 - Build Date:Oct 21 2019 - Build Time:13:49:09 000000.001| OKAY| Initial working directory: "/" 000000.001| OKAY| Working directory changed to "/Applications/League of Legends.app/Contents/LoL" 000000.001| OKAY| Current process: "/Applications/League of Legends.app/Contents/LoL/LeagueClient.app/Contents/MacOS/LeagueClient" 000000.001| OKAY| Command line arguments: 000000.003| ALWAYS| Direct Launch enabled for league_of_legends.live in environment 'live' for app path '/Applications/League of Legends.app/Contents/LoL/LeagueClient.app/Contents/MacOS/LeagueClient' and install dir '/Applications/League of Legends.app' 000000.004| ALWAYS| Found Riot Client live install (/Users/Shared/Riot Games/Riot Client.app/Contents/MacOS/RiotClientServices) 000000.005| OKAY| Launched Riot Client with process 13506 000000.005| ALWAYS| Riot Client started. Exiting with the expectation of being restarted (ExitForDirectLaunch). 000005.007| OKAY| EventCollector: 0 events remaining after thread join 000005.007| OKAY| Shut down EventCollector in 0 milliseconds

So It seems like the game "expects" to be restarted but it doesn't happen.

I know some things are expected to happen with Catalina but i still run Mojave 10.14.6. My MAC user has admin privilegies on the system

What i tried:

• I tried to re-install the client multiple times but no luck. I tried also the PBE launcher and exact same behaviour
• Reboot my MAC
• Cleanup memory with cmd+opt+P+R when starting my laptop

Everything failed.

any ideas?
