Hi,
This looks like a redirect issue created by a plugin, do you have any plugins for security, hiding wp-admin, redirecting wp-admin or wp-login.php?
You should disable all plugins except for BuddyPress and Elementor, disable caching and try registering / activating again in an incognito window. If the issue is no longer present then it is being caused by a plugin. Please let me know your findings from the above test.
