Did you enable Autologin at the installation?
Because in the logs i see it tries to get into the Plasma Wayland Session, which is segfaulting and reason you dont even see sddm.
I think I clicked on a option like that?
Yes, then reinstall and dont click on it.
Actually we can not do anything, if your GPU has bad support for wayland. Since Plasma 6 wayland is the default session and if you click on auto login, it will of course use the default session.
In the above logs, you can see that your complete GPU and CPU is segfaulting with massive of issues.
You should report this to the kernel/mesa developers.
