1. Is the TFS running? My guess is not.
2. Set the log level to notification.
3. Run the TFS from commandline using the -x option : https://wyday.com/limelm/help/turbofloat-server-commandline/
4. Disable all firewalls / anti-virus except Microsoft's Windows Firewall and Microsoft's AV (Defender). All 3rd party AVs are at best, junk. At worst, malicious programs doing the work for hostile foreign governments.
5. If you did step 1-4, and the TFS display in the commandline doesn't show any connection then try PING ing the local server. You might be inadvertently running on a different port, or binding to a different address.
