PHPExcel Codeigniter-4 unable to upload more than 50k rows

I want to upload an excel file of 50K columns but it’s unable to read them while I upload 2k row its worked fine and data was uploaded in the database(MySQL) also but when I tried to upload 50K rows at a time its not even showing error also.So my requirement is to upload 50K rows and 40 columns at a time using SpreadsheetReader_XLSX
