Note that I have no clue what the launcher version is specifically, but it must be the newest. Loaded into the launcher and it said a new version was available so I downloaded the .deb package and installed it. The login screen appeared and I could successfully login, but it led to a blank screen even when I close and start the launcher again. Screenshot is attached.
Can you attach the
launcher_log.txtfile please? It should be located directly in yourminecraftfolder. (Unfortunately I don't know exactly where that folder is on Linux)
