v0 deleted all data of my web

i wrote to change a single tab of my web page but v0 deleted all previous codes and made new code files which contain that specific tab

i didnt deployed it but i am also unable to reterve my old page so that i can edit it further

the old site was this -

https://sunchkofficialwebsite.vercel.app/

the bot destroyed and made it this - https://kzminauseqre2ihdpzso.lite.vusercontent.net/
