Error proc_open on Process() class

I get an error like this:
"The Process class relies on proc_open, which is not available on your PHP installation."

even though I have created a .user.ini file like this:
disable_functions="exec,shell_exec,passthru,dl,eval,assert"

The error seems to appear because of this code:
new Process([.....]);

Previously on the s7.serv00.com server I did not experience this error. how do I fix it?

Im using hosting on server s16.serv00.com to host my laravel project.

udinmauludin For this purpose, you need to unblock exec for PHP in the panel. There is information about it on the help page: https://docs.serv00.com/WWW/#php.
