PLEASE HELP. My Mac crashed (frozen screen) with 4 different windows opened in brave browser, each of them containing ~20 really important tabs. After rebooting I opened brave, which offered to restore windows/tabs as usual. But this time nothing happened when I clicked it, only a blank window opened up.
When going to History, brave does not show/offer x number of tabs and cmd + shift + t does not work.
After reading all relevant forum posts regarding this issue, I quickly went to Library/Application Support/BraveSoftware/Brave-Browser/Default/Sessions and made a copy of the folders Session Storage, session_profiles and Sessions. The Sessions folder contains 4 files, 2 of them called Session_unixtime and 2 called Tabs_unixtime. I checked them and each one of them got changed before the crash. “Yeah” I thought, closed brave and tried to replace the current files with them - but this didn’t work and there were no tabs after opening brave again.
Does anyone have experienced this or even have an answer/manual to restore tabs? Counting on @Mattches here 
THANK YOU
