PHP error after upgrading

Hi.
Ten minutes ago I upgraded three among
* Regular Labs - Conditional Content
* Regular Labs - Content Templater
* Regular Labs - Modals
* Regular Labs - Sourcerer
One has been upgraded days ago, but I don't remember which one...
Now on the frontend I get a blank page with an error message:

0 - RegularLabs\Component\Conditions\Administrator\Helper\Convert::prepareSelection(): Argument #2 ($params) must be of type object, array given, called in /var/www/vhosts/marcofioretti.it/subdomains/alter/httpdocs/administrator/components/com_conditions/src/Helper/Convert.php on line 42

What can I do?

Same here on some website. One website had a conditional content item in an article that caused the problem. Removing the content fixed the broken link.

Development release of Conditional Content works fine!

Conditional Content Dev is OK for me too

I wonder if the developer monitors his php error log. There seems to be many php related errors. One fix leads to another error, please QA thoroughly before release. Thanks.

Thank you for your reply and thank you for the excellent product. I'll stick with the product. I am too lazy to find other products, and not sure whether other products will be better than yours.
