I just noticed that 3.33.3 released . the issue is solved now.
The issue is if you create a “contianer” from elementor > template > create template , and add it via it’s shortcode to a page or a post , product etc … styles does not load for that rendered part.
its not about any other plugin or additional code. the page with a broken render “container” shortcode has also a broken menu widget if used.
there are absoulote relation between the a page with “container template” elementor short code and menu widget.
