Unable to restore my whatsapp backup from google drive

[Android Central Question]

Same phone number but switched phones from old Phone A to new Phone B Took the backup from old Phone A, and I can see it on my google drive. The old one Phone A was reset to factory settings. Installed WhatsApp in new Phone B, but when I try restore from google drive, it got stuck at 24% or sometimes 40% while 'Restoring messages'. Can't restore. I also tried to restore on old Phone A, but same problem. Please help what are my options to restore my ONLY backup that is available on Google drive into the new Phone.

Below is the response from Whatsapp team:

"It appears that your backup is corrupted.
You must have the same phone number as when you backed up your chats in order to restore them.
Unfortunately, we can't help you restore corrupted backup files."

I did not really understand how this app created a corrupted backup and put it on google drive?

It's possible it did get corrupt, not sure how but can happen.

Ugh, usually that's the problem. Before giving up you could try to restore that backup file in the old phone and see if it can read it. It's a long shot but there's not much else I can think of.

Another thing to try is uninstall WhatsApp from your new phone (force stop and clear data/storage first), use a file explorer to delete any file or folder left behind and install again.
