Solved

While LeoCG is correct, the /Sessions/ directory overwrites itself constantly.

However, if you regularly backup your system, restoring the
AppData\Roaming\Opera Software\Opera Stable\Default\Sessions
folder restores your Opera window and tabs.

@leocg
I would greatly appreciate more explicit instructions.

I had four Opera windows open.
Opera closed. When I reopened it, only one window opened.
In AppData, I found the "sessions" and "tabs" files shown below. (I created copies, just in case.)

Notably the latest "sessions" and "tabs" files from 13:27 and 13:02 are considerably smaller, consistent with there being only one window open.

How do I restore one of the previous sessions? or tabs?

Thx

Windows 10 crashed during an update.
I have a backup. It restores, but I can't log in for some reason.
However, I can see all the files in the *.TIB files.

Is it possible to extract the open sessions from a file somewhere on the SSD? (I had three open session, with 10-12 tabs each).

I was also using TabHamster to save sessions. Is that recoverable?

Thx

Opera recently updated, and TabHamster does not work. Clicking on it does not open anything below.

When trying to use Google Duo, I get the error message
"Something went wrong.
Duo for web can't access the camera or microphone"

I have given permission for both.
The following website can access the devices: https://webcammictest.com

I am running Opera 67.0.3575.97 on Windows 7. Restart didn't help.
On my Android phone, Duo works.

Any idea what the problem is, and how to get Duo working?
