Welcome to the forums. 
Hope you’re doing great.
If you have the “2FA” activated already, I ask you for a bit more of patience, it might not take the same amount of time for all the accounts.
As recommendation if you didn’t do so, when you have a chance please contact steam to check if everything is okay.
After contact steam, If you’re still with this issue playing Lost ark, we like to take a closer look into this issue with you, when you have a chance, please use the link here to speak with our Customer Service team:
Also please make sure you send this link to the support staff so they can help you better and please let me know how was it!
Hope this helps.
