Bitcoin Node GUI quits immediately

My node was running fine until I decided to change a setting in the network tab. I checked the “Use a separate SOCKS5 proxy to connect to peers through the Tor onion service” box and entered 127.0.0.1:9150 for the port in the Proxy IP box. Box 9150. When I try to restart the node, it no longer starts, gives “Error 127.0.0.1:9150 Invalid proxy”, and quits immediately. How do I restart a node? The GUI doesn’t even start. I just started exploring Bitcoin nodes and have absolutely no knowledge. Any help would be greatly appreciated. I’m running Node on Debian Linux.
