@balopina1 Yeah I am having the exact same issue and nothing is working. I can sign in on google perfectly fine though except it doesn't have the in-built VPN which sucks.
Open Windows Explorer and go to C:\Users<USERNAME>\AppData\Local.
Right-click the Google folder and select Properties.
Go to the Previous Versions tab. ...
Choose a version that is dated before the history was deleted and click Restore.
@kentb Since it is a non-Opera website I can't vouch for the security of any files there, but https://www.kyleabaker.com/goodies/opera/download-old-opera-versions/ claims to have versions as far back as 2.0. I remember running Opera 3.51 on my old Windows 98 laptop, though as you're talking about 20+ year old software I can't imagine any site still supporting it.
