Local environment error 500

Hello, thanks for your plugin.
Im running a wordpress instance on my local computer using MAMP. Does it work on local installs?
I have a 400mgs database with about 8 years of image uploads. its very heavy and some folders have around 5000 images. The files are also not in the uploads folder, I have them on a media folder outside.

Trying to run the plugin but get all 500 errors. In the network console I see the error is an admin-ajax.php, after a few seconds it runs it again and then the same file is corrected and gets to status 200, any ideas? Thank you again
