League of legends won't open when I click on play in the launcher

I am trying to play League of legends on my Arch Linux machine but it won’t open yesterday it work
sometimes but now it’s broke. In Addition, I’m trying to start it on my Nvidia Card but that doesn’t seem to work either. I have the optimus-manager and my system runs in hybrid mode.

have you checked the troubleshooting steps regarding nvidia and optimus on laptops/desktops? If you have an AMD card in your PC, make sure to check the following:
Right click on the game in lutris → Configure → System options → make sure that it says “Nvidia Proprietary” on the option named “Vulkan ICD loader”.

Check these links, these are post-install and troubleshooting steps from the creators of the League of Legends install script in lutris:
