PHP Warnings

Hi,
Is Arcane Theme going to get a new update?
I started to get these 2 php warnings today.

-PHP Warning: Trying to access array offset on value of type null in /srv/htdocs/wp-content/themes/arcane/header.php on line 267

-PHP Warning: Undefined variable $lwa_data in /srv/htdocs/wp-content/themes/arcane/header.php on line 267

The top bar menu wasn’t showing correctly. It only did a list of all the pages on the top left corner. I re-generated Critical CSS Loading and it looks like that fixed the issue.
But I’m also running into an issue with Elementor not wanting to load the pages fully. Not sure if it has anything to do with the theme.

But mainly WordPress is flagging Arcane Theme PHP.
