Costumizer Problems with GP Premium and Elementor

Hello,
if I activate more than six components of Gp Premium my costumizer doesn´t load. I get an internal Server error 500 in the costumize.php. This only occurs when Elementor is activated, but only with Elementor Pro. After deactivating Elementor Pro an activating it again I get this error:

For me this is way to complicated and I dont know what I can try to get it working.
Thank you for your help.
