Librairy CEGCore error after installation plugin Chronoforms 7 with Wordpress 5.5

Hello all the team,
i've a blank page with this message when i click on the Chronoforms7 menu item : Your PHP version should be 7.0.0 or later. Please download the CEGCore framework from www.chronoengine.com then install it using the 'Extensions Manager'
-----------
Versions :
Chronoform 7 RC2
Wordpress 5.5
PHP 7.2.32
----------
Some pb with the class "WordpressChronoG3" in line 49 of the chronoforms7.php file?

if(!class_exists('WordpressChronoG3')){
 die("Please download the CEGCore framework from www.chronoengine.com then install it using the 'Extensions Manager'");
 return;

Thanks a lot if you can help
JB
