Where userstyles are stored locally on the computer?

I reinstalled browser and somewhy all userstyles are gone. Last userstyles backup was made a whole half year ago. But! Before reinstalling the browser, I made a backup of a whole browser folder (including User Data), so how can I get my userstyles from a backup?

Exit the browser, create IndexedDB in the new profile and copy clngdbkpkpeebahjckkjfobafhncgmne (this is an id of Stylus extension) from the old profile's IndexedDB. Do the same for Local Extension Settings and Sync Extension Settings.

I tryed to do that, but styles just cleared (as they where after reinstall. I wasn't cleared Browser's AppData when reinstalling)

Can I extract pure css from the backup?

If you can launch the browser (downgrade maybe?) from the backup profile then it should be pretty easy to export those data. Otherwise you may have to try finding the database and extract the data using some kind of database management software.
