Can’t activate Slider Revolution on a server hosted directly at Elementor!

I tried to aktivate Version 6.6.8.
If i use “Woodmart – Plugins” an click “Install”, the hourglass “ring” spins but nothing happens!
I’ve also tried deactivating Elementor during installation, but that didn’t change anything either!

The hourglass goes on forever.
When I look at the WordPress plugins, however, I see that the “Slider Revolution” plugin has been installed in version 6.6.8.
But when I try to activate it I get the error message:
“The plugin cannot be activated because it generates a fatal error.”
