Kde sddm cannot start

[wlmosv]

Hi everyone, I installed kde on my gentoo but I used depclean and accidentally deleted a lot of things including kde. After I reinstalled kde, I found that my desktop could not start normally! First of all, I want to explain that I use the openrc system. Since I can only take pictures, I will put the screenshots below later. The problem now is that I have set the displaymanager to sddm. The displaymanager can also start normally, but the screen is black. I don’t know how to solve it. Before this, I installed nvidia, but now it seems to remind me that the nvidia module has not been initialized. I use the kernel compiled by genkernel, but I don’t think it has much to do with nvidia.
