500 Error post installation

Hi all, I'm having a lot of trouble installing Opigno. I first tried installing through composer, but I'm having trouble with the memory limit, so I decided to just download a .zip to install. I got through all the steps, and proceeded to go to the homepage, which is localhost:8888/opigno ( I run MAMP for this setup ). What happens is a WSOD. I checked my error_log, and it's giving me this particular error: [18-Dec-2019 11:52:17 Europe/Amsterdam] PHP Fatal error: Maximum execution time of 0 seconds exceeded in /Applications/MAMP/htdocs/opigno/profiles/opigno_lms/modules/contrib/h5p/vendor/h5p/h5p-core/h5p.classes.php on line 909 This also happens on the login page, so it kinda blocks me from disabling this module. Does anyone have experience with this problem and can help me out? Thanks in advance! EDIT: The same problem occurs when installing opigno through composer.

500 error

even if you install from zip, the memory requirement is still needed. Do that first, and then install with composer, its easier that way.

Agreed, but my memory limit

Agreed, but my memory limit is even set to 1024 mb and this still doesn't seem enough to install from composer. PHP Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 67108864 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/Solver.php on line 223 So a normal install seemed logical to go to as a next step.
