I've attached a few log dumps of the issue and tagged numbers to them.
1) My own log, using the command args PROTON_LOG=1 WINEDEBUG=warn+all
2 & 3) A discord user's similar issue with the command args PROTON_LOG=1 and PROTON_LOG=1 WINEDEBUG=warn+all being used respectively.
As of the most recent major update, I cannot launch the game, I only see the Deadlock Offline text and Loading for half a second before it closes the game.
No .mdmp crash logs exist within the Deadlock directory, and nothing was modified within the game files.
I am running Nvidia Driver...
