External hard drive freezes when copying files

Hello, I have 4tb WD external passport hard drive and already used almost 1.2tb space but recently im not able to open some of my folders in drive.
its show this error : Screenshot, 2022-11-22 20:02:36 - Paste.Pics

Also i run chkdsk command to fix the errors, its took more than 24hour and complete 37% (showing only bad sectors and nothing else), i cancelled the chkdsk command and close the cmd

After facing this problem i contact with wd team for warranty claim and solution, they told me to take backup of your data and send the drive to service center, so they can check it from their side.

But when im trying to copy my data from my external drive its get freeze. And i cant do anything even i have to shutdown my laptop and restart again (this problem im facing again and again) not able to copy my important data.
From more than week i only recovered 2gb data from my 1.2tb total data.

This problem is actually horrible for me cuz those 1.2tb data is actually very important for me, its my 12years work data that i stored in my 4tb external drive and i don’t have any other backup.

Please help me with this…
