IM having the same problem but I couldnt solve it

$spreadsheet = new Spreadsheet();

    $sheet = $spreadsheet->getActiveSheet();
    
    $sheet->setCellValue('A1', 'GeeksForGeeks!'); 
    // -rw-r--r--
    $sheet->setCellValue('B1', 'A Computer Science Portal For Geeks'); 
    
    $writer = new Xlsx($spreadsheet);
    
    $writer->save('gfg.xlsx');

Its just a test for me, when Im going to save it appears this problem i have the URL good, i had to change the permissions to 777, its not root anymore, its my name, i dont know what else i have to do.

I also checked this URL https://unix.stackexchange.com/questions/503111/group-permissions-for-root-not-working-in-tmp but nothing works.
Thank u everyone
