I installed OpenVPN on my raspberry pi 3b+, I had some problems while trying to connect to the VPN server I tried some solutions after that the terminal on the raspberry pi changed its name.
I reboot the Pi and suddenly I got into a GUI interface asking for Password I've tried my own password and many more nothing worked.
then I took the sd card out connect it to ubuntu machine, and now I found out that the folder Home which has Pi folder is empty and all my 6-month work was saved there so, please I need help to recover my files or fix this issue.
