I am trying to attach a content type to a page layout

private void attachContentType(string siteURL, string path, string filename, ClientContext ctx, string folderName)
        {
            Web web = ctx.Web;
            Microsoft.SharePoint.Client.File home = ctx.Web.GetFileByServerRelativeUrl(web.ServerRelativeUrl + "/" + folderName + filename);
            ctx.Load(home);
            ctx.ExecuteQuery();
            home.ListItemAllFields["ContentTypeId"] = web.ContentTypes.GetByName("Page Layout").Id;
            ctx.ExecuteQuery();
        }

This does not throw any error, but when I edit properties of the pagelayout, its still showing Design File only

    I think home.ListItemAllFields.Update(); was missed.

I think you missed home.ListItemAllFields.Update();

home.ListItemAllFields["ContentTypeId"] = web.ContentTypes.GetByName("Page Layout").Id;
home.ListItemAllFields.Update();
ctx.ExecuteQuery();

Try the below code. Note, it will only work on the RootWeb, so you might need to the change the web object accordingly, somewhat like Web web = ctx.Site.RootWeb:

Web web = ctx.Web;
List list = web.Lists.GetByTitle("Master Page Gallery");
ContentTypeCollection contentTypeColl = list.ContentTypes;
ctx.Load(contentTypeColl);
ctx.ExecuteQuery();

ContentType contentType=null;
foreach (ContentType ct in contentTypeColl)
{
    if (ct.Name == "Page Layout")
    {
        contentType = ct;
        break;
    }   
}

Microsoft.SharePoint.Client.File home = ctx.Web.GetFileByServerRelativeUrl(web.ServerRelativeUrl + "/" + folderName + filename);
ctx.Load(home);
ctx.ExecuteQuery();
home.ListItemAllFields["ContentTypeId"] = contentType.Id.ToString();
home.ListItemAllFields["Content Type"] = contentType.Name;
home.ListItemAllFields.Update();
ctx.ExecuteQuery();
