Magento 2 Dies When Creating a Configurable Product with 2000 Configurations

I need to add configurable products with lots of configurations like 2000 and even more. I want to do this through Admin Panel but Magento virtually dies when I click Save.

Then I need to reboot the whole server in order to revive Magento.

Is there any solution for that? Will it work better and faster if I install Magento locally on MacBook?

It’s Magento 2.4.1.

Thank you very much in advance!
