Hello Jorddz.-,

Please follow the steps posted above by Ubi-Houck.

They are a proven fix for this issue where Epic will ask you for a key. You will need to delete your Uplay cache and ownership folder after backing them up somewhere safe.

After that I would suggest -

Make sure to reinstall the latest Uplay launcher from our website here -
https://uplay.ubisoft.com/en-GB

Make sure Epic, Uplay and the games file is set to run as administrator -

- Right click on Uplay.exe, Epic.exe and the Siege .exe files
- Select 'Properties'
- Select the 'Compatibility' tab
- Check the 'Run as Administrator' box
- Click 'Apply' then 'OK'
- Do this for Uplay, Epic and the games .exe file
- Finally, try launching the game from its .exe file

Let us know how you get on after trying Ubi-Houck and my troubleshooting steps, unfortunately there is no easy method to correct Epic asking for keys, but these steps should be able to solve your issue.
