@leocg Thank you for the reply.
What third party tools can I use to decrypt, if any?

And how would I ensure OperaGX does not delete my newly entered passwords as they disappear after being added?

Operating System: Windows 11 Home
TPM: Intel TPM 600.18.25.209
Browser: OperaGX

After running net user to change my password of my local account due to not being able to key in the password due to hardware, all my passwords in the OperaGX password manager no longer appear. They are in the Login Data file, but are all encrypted, thus the system appears to be unable to decrypt them. Cookies and previous sign ins also appear to have been removed.

I only possess backups of OperaGX Appdata after the net user password change (Login Data, Cookies, etc). When using net user to change the password of my local account, my device had Windows Hello and an alphanumeric Pin.
TPM status is "ready for use" (after changing Windows password back to the one before running net user).
Attempting to change the Windows password back did not reveal my OperaGX passwords either. I am not logged in or synced on OperaGX so I am unable to retrieve my passwords from the cloud.

Which of OperaGX's files would be able to decrypt the passwords to retrieve my passwords? Otherwise, what steps can I take to retrieve my old passwords which are no longer visible?

Thank you.
