Error in production mode on RoR 7.0.3.1 with Bootstrap 5.2

[Sega]

Ruby 3.1.2
Ruby on Rails 7.0.3.1
Third party library: Bootstrap 5.2 ( new version 5.2 released )

With bootstrap 5.1.3 (previous version) all works fine!

app/assets/config/manifest.js :

//= link_tree ../images
//= link_directory ../javascripts .js
//= link_directory ../stylesheets .css

//= link lib/bootstrap/5.2.0/js/bootstrap.bundle.min.js
//= link lib/bootstrap/5.2.0/js/bootstrap.min.js
//= link lib/bootstrap/5.2.0/css/bootstrap.min.css

in view stylesheets and javascripts are attached via stylesheet_link_tag and javascript_include_tag

config/environments/production.rb :

config.assets.css_compressor = :sass
