Theme crashing; uncaught PHP Fatal Error in AcmePhotoPro

I purchased this theme last year and it worked fine (version 3.0.2).

Then I was forced to renew the theme (which has been updated to version 3.0.5). That’s when trouble began.

Logging into WordPress (current version 5.9.3; PHP 7.4.29), the system crashes and locks me out of WordPress entirely. Via the command line I was able to restore to another theme to get access to WP.

In the debug and apache logs was the following error:
PHP Fatal error: Uncaught Error: Attempt to modify property “no_update” on bool in /var
/www/WPSITE/public_html/wp-content/themes/acmephotopro/acmethemes/updater/theme-updater-class.php:125

It appears that AcmeTheme developers need to update the theme to play nicely with the Updates API:

Recommended usage of the Updates API to support the auto-updates UI for Plugins and Themes in WordPress 5.5

I'm not happy to have (re)bought a theme that crashes WP; buyer beware.
