            if (!item["FileLeafRef"].ToString().Contains(".tmd"))
            {

                item[propertyName] = propertyValue;  // this line is cause of error
                item.Update();                       // this line is cause of error

    ExecuteQueryWithRetry(clientContext);

I tested the code snippet below to update file items' Title property in my side, it's working as expected:

            using (ClientContext ctx = new ClientContext("https://tenant.sharepoint.com/sites/dev/"))
            {

                ctx.Credentials = new SharePointOnlineCredentials(account, secret);
                ctx.Load(ctx.Web);
                ctx.ExecuteQuery();

                List targetList = ctx.Web.Lists.GetByTitle("Documents");
                ListItemCollection ItemCol = targetList.GetItems(CamlQuery.CreateAllItemsQuery());
                ctx.Load(ItemCol);
                ctx.ExecuteQuery();
                foreach (Microsoft.SharePoint.Client.ListItem item in ItemCol)
                {
                    if (item.FileSystemObjectType == FileSystemObjectType.File)
                    {
                        if (!item["FileLeafRef"].ToString().Contains(".tmd"))
                        {

                            item["Title"] = "TestTitle";  
                            item.Update();                       

                        }
                    }
                    ctx.ExecuteQuery();
                }
             }
