Starting with macOS 10.15.4 the above “Legacy System Extension” message will be shown when Little Snitch is installed.
I now think Little Snitch is the culprit. The Problem is, I'm not sure what to do about it. So, a lot of my Tor Sessions stop working midway through. I uninstalled Tor Browser and reinstalled. It worked fine until the second use. Then I went to LS and made sure to allow all connections. It worked okay, for about 5 minutes before reverting back.

Little Snitch is a host-based application firewall for macOS. It can be used to monitor applications, preventing or permitting them to connect to attached networks through advanced rules. It is produced and maintained by the Austrian firm Objective Development Software GmbH.
Unlike a stateful firewall, which is designed primarily to protect a system from external attacks by restricting inbound traffic, Little Snitch is designed to protect privacy by limiting outbound traffic.[2] Little Snitch controls network traffic by registering kernel extensions through the standard application programming interface (API) provided by Apple.[3]
If an application or process attempts to establish a network connection, Little Snitch prevents the connection. A dialog is presented to the user which allows one to deny or permit the connection on a one-time or permanent basis. The dialog allows one to restrict the parameters of the connection, restricting it to a specific port, protocol or domain. Little Snitch's integral network monitor allows one to see ongoing traffic in real time with domain names and traffic direction displayed.
The application (version 4) received a positive 4.5/5 review from Macworld.[4]
