Which of the two profiles are you using as your current profile folder ?

Is that the default-release profile ?

Are there compressed .jsonlz4 backups in the bookmarkbackups folder in either profile that can be used to restore bookmarks ?

  • Bookmarks -> Show All Bookmarks -> Import & Backup -> Restore

If you lost personal data then it is possible that a new default-release profile folder has been created. See "Determine if Firefox has created a new profile":

Firefox 67 and later can use a dedicated profile for each of the Firefox update channels.
For Release versions this profile would be a xxxxxxxx.default-release profile, profiles used in older Firefox versions usually used a xxxxxxxx.default profile (a refresh adds a time stamp).

Note that with the default profile in the third screenshot there have been multiple issues with saving prefs.js as there are a lot of numbered temp prefs-##.js files.
You can check the file dates to see when this happened.
