Hi @nobita!
The problem is, that the customizer will not be available correctly when I use WP5.8.
This ia a screenshot from the widget-editor when wp5.8 is installed:

And this is the damaged customizer:

Available php-version on my server are: 5.6, 7.0, 7.1, 7.2, 7.3, 7.4, 8.0
Actually set is php 7.4. But this fault appears also when I activate php 8.0.
Actually I have installed WP 5.7.2 with raindrops and the customizer and widget-editor works perfectly.
Thanks for your help!
