Minecraft sky flickers on the shader?

I have the problem in Minecraft that when I activate a shader, the sky flickers. I use the shader "seus-v10.1-standard" and have also used it with others, such as Tried the "RudoPlays Shader". However, neither did it change my problem. Can someone help me there?

You probably have to deactivate clouds in the graphics settings

The clouds didn't fix it, but the sky did. I had turned off the sky. Thanks for the tip, otherwise I wouldn't have seen that.
