Steam Session's Listen Server Incompatible Build Issue

Dear saviors,

Using the Advanced Sessions plugin, I’m simply trying to get a created/found session through the Steam Online subsystem. There’s gotta be some setting missing or something DUMB that I’m doing.

On advice from the Unreal discord, I re-build my setup in an empty project for troubleshooting. Steam Overlay is working and recognized, “Has Online Subsystem” node returns true, and logs are indicating that this issue is related to an “Incompatible Build” on the server side, when trying to create a listen server. This is on the “480” DevID for generic development.
