Problems after Pro update to 3.1.14

It seems that Athemes has dropped the ball and refuses to respond to tickets. I raised 3 within a week and none have been answered.

In any case, I hope that there is someone here who may have experienced a similar issue and thus will be able to help with the following:

After the latest update, two of my websites experienced problems and I had to restore both from backup. The first one, 'haltonpeelhumanists.ca/' gave me the following error through the WordPress built-in feature for errors:

When seeking help with this issue, you may be asked for some of the following information:

There were problems with the Theme Dashboard as the help was not working and the area at the bottom pertaining to siteorigin was giving an error

The second site, was just giving me the following error when accessing the Theme Dashboard: implode(): Argument #1 ($pieces) must be of type array, string given

Interestingly, the sites experiencing issues use SiteOrigin for page builder. However, the sites that use Elementor, did not experience any issues.

I would be most grateful if anyone is able to assist me in this issue so I can update the theme to the latest version.
