WP Critical Error after Lay Theme update

[gg]

Hi I've been working on a simple film portfolio page for a client with a few assets & embedded videos from YT/Vimeo since quite a while. I was running into issues updating wordpress and whenever I tried updating Lay Theme, it failed as well.

Now i manually updated WP via SSH access successfully, now when I tried updating Lay theme, WP throws a critical Error. It also did that before I upgraded.

I am able to access WP dashboard if I rename the lay folder via SSH/FTP. Not sure but could the solution be to do a clean lay theme install and you provide a new license key for it?

can someone help me/point me into the right direction here? please see screen captures for context

I was having issues since starting to work on this and my client already purchased 2 lay theme licenses since nobody replied to his emails.
