[Fixed] I had a stylus script to have more youtube thumbnails in home page which broke today after 2 years of working, can any one help?

[Rohith_Kumar_Sp]

was using this 
 

ytd-rich-item-renderer {
width: calc(100% / 6 - 16px - 0.01px);
}

#avatar-link.ytd-rich-grid-video-renderer {
height: 25px;
}

#avatar.ytd-rich-grid-video-renderer {
width: 25px;
height: 25px;
}

ytd-video-meta-block[rich-meta] #channel-name.ytd-video-meta-block, ytd-video-meta-block[rich-meta] #metadata-line.ytd-video-meta-block{
font-size: 1.1rem;
}

#video-title.ytd-rich-grid-video-renderer{
font-size: 1.4rem;
}

Now this happens 

 

script 2 also worked 

 

#page-manager.ytd-app {
       margin-top: var(--ytd-masthead-height, 40px);  
}
#contents.ytd-rich-grid-renderer{
