That looks as if the boot from the internal µSD card process couldn't get started. You might want to try the manual factory reset procedure.
- Charge your Libra 2 preferably from a wall wart for at least an hour.
- Hold the power button down for at least 30 seconds to force a power off.
- Press and hold one of the page turn buttons.
- Continue to hold the page turn button and press and hold the power button.
- After 30 seconds or so, the screen should change to the resetting screen.
- You can now release the power and page turn buttons.
- If the process succeeds, your Libra 2 will be wiped back to factory and will need to be setup from scratch.
If this doesn't work, post in the
Kobo µSD Card Image Requests thread to request a firmware image for your Libra 2.
Good luck!
