Splash Screen freeze after changing kernel

Hello everybody,

I’ve recently changed my kernel from 5.8 to 5.9 I’m new with manjaro and Linux in general but I wanted to give it a try. After several days I noticed that my computer was slower and the the gui app would crash. So this afternoon I changed back to the kernel 5.8. however since then I can log in and enter my password but the splash creen always end up freezing. I’ve tried to switch to kernel 5.4 but it does the same thing.

I’ve searched an answer and end up on this forum :

But the instructions didn’t helped me.

Thank you by advance for your responses.
