Browser tabs disappeared.

Please someone help me, I’ve been using Brave for a long time, I always leave several tabs open with important notes. Today I opened the browser and it started from scratch, without any tabs, I tried using Ctrl + Shift + T to reopen them and it didn’t work. I don’t understand, it disappeared with all the tabs that were open. Can someone please tell me how to recover them? They are also not in the history, and this happened with all the profiles here on Brave, all the tabs that are always open are gone.
