Same here - clicking “Play” makes it say “Launching” for two seconds, then it’s “Play” again and nothing happens…

PS: Tried scanning game files and restartet my PC, did’t help.

Elkay-1863 · June 30, 2026, 5:25pm

Same. Apparently someone mentioned this was also broken on the PTR and they didn’t fix this before launch?!

BaneAndy-1422 · June 30, 2026, 5:27pm

Can’t get in on a steam deck same problem.

Stitchless-2872 · June 30, 2026, 5:28pm

Same issue here.

zakhar-2337 · June 30, 2026, 5:29pm

Can’t login from Battle.net on Windows either

Elkay-1863 · June 30, 2026, 5:32pm

Not the same issue. This is specifically diablo_iv_loader.dll hard crashing for Linux users when they try to launch the game.

Sepp-1869 · June 30, 2026, 5:37pm

Same issue. on CachyOS

tired-11286 · June 30, 2026, 5:38pm

I am also encountering this issue.

Psyolia-21243 · June 30, 2026, 5:41pm

same here, nixos using cachyos proton 11.0

Consp-2735 · June 30, 2026, 5:42pm

Considering it’s a dll from blizzard which is crashing (by the looks of it via proton logs) I’m not surprized everyone failes to start.

Klinger-21631 · June 30, 2026, 5:43pm
