This looks like it might be a similar issue to the one I am still having:
https://ww.wp.xz.cn/support/topic/the-plugin-breaks-wp-admin-still/
You might be getting caught in that same redirect loop as me, which end up with a 503 error. Maybe try logging in directly to the /w-admin/index.php file, as works for me?
I’ve not had any feedback on that thread linked to above, and I was removed from the previous one I was in, about the same subject. This is a real problem for me, as I’ve bought quite a few expensive addons from WooCommerce, and the client needs to use WooCommerce Admin to work with those plugins. They currently can’t even use WordPress Admin with this plugin active.
Hopefully someone can look into where the conflict with this plugin is happening. None of the systems I use, such as wp-config.php debugging mode, or browser developer consoles are returning any errors. Also, this issue happened on a fresh install of WordPress with only WooCommerce plugins in place.
Help badly needed!

@matstillo Thanks for this info. Do you have a list of plugins you are using in the instance described above? I’d love to be able to reproduce what you are experiencing locally.
Thanks
