Is Sync turned off on the device in question?
I recently deleted all my passwords (Cookies, and so on) from my son's PC, and was supposedly signed out so it was only supposed to do this on that machine, not across all devices.
Luckily I had a PC that is only used every couple of weeks that hadn't synced.
I turned the WIFI off, went in to chrome Password Manager, then settings, then exported all passwords to a csv file. I was then able to import these to the machine that was online and hit sync and all is restored.

Can I see saved Passwords in Chrome?
You can see passwords saved in Google Password Manager by going to your Passwords icon under your profile, or by accessing your Settings > Autofill and passwords > Google Password Manager. Then, click on the site you want to view the password for to view its details, and click the eye icon to reveal the password.
Can you see old passwords saved in Google?
You can't view old passwords saved in Google, but you can recover your account and password information by accessing Google’s account recovery link. You'll need to enter your email address or phone number and follow the online instructions.
How do I find my Google password without changing it?
You can't simply navigate to Google Account settings to view your password using Google Password Manager. Unfortunately, you can't view your Google password without resetting it. While this seems like a hassle, Google and other companies don’t store your passwords in a way that allows recovery.
If you want to save yourself the frustration in the future, we recommend using a password manager to store your Google account password. That’s a secure way to keep your passwords on hand without having to write them down or remember them.

I had the same issue after updating Chrome on my Mac yesterday. All saved username and passwords disappeared from password manager, but were still all there in passwords.google.com. And saved info was not autofilling for login to any websites. Spent hours searching the internet for a solution to no avail.
Then I resorted to restarting my laptop, and suddenly password manager was intact again upon restart, and website login autofill was working again as usual.
