The irony of this situation is that when I do re-connect the ethernet, UE-5.1.0 crashes as soon as a connection is made.
Upon digging a bit further, I went and disabled “Enable transport” in the UDP section of the project settings. This allowed me to reconnect my ethernet cable. The editor still crashes when I have internet and try to open it regularly, however.
Do you know what ports I might need to open for “Enable Transport” to work, or what “Enable Transport” does and how I might troubleshoot this? It looks like that option is what’s making this crash.
