Same thing. 2 secs and then nothing

I'm noticing that Talos91 just updated the handler on 6/2/2023, but I am experiencing a failure to load the game with Nucleus Co-op.

When I click "Play", the game briefly shows for two seconds, then disappears. After that it does nothing, what can I do to fix it? I have a new copy of the game and of the handle.

Gracias. n.n/

[KrEi-Z]

is there a list of supported games? or is it just L4D and AS?

I can't seem to figure out where my screenshot went, but basically, it has one gamepad and no keyboard option.

[4lw]

ok, hold on.

[Dimaxa]

take screenshot

[4lw]

i mean alpha 8 not 0.8

[4lw]

it has the gamepad, but I only have 1 gamepad and would like to play 2 player splitscreen, meaning the kb/m would need to be there.

[4lw]

there is no keyboard icon, I have 0.8 too. :(
