Symptoms
the Game will silently fail to launch, without showing any window or error dialog.
according to Proton's logs, the Game trying to load CrackProof kernel module and fails because of lacks WDFLDR.sys.
3596.978:0078:0084:err:module:import_dll Library WDFLDR.SYS (which is needed by L"C:\windows\SYSTEM32\usrdrv017864.sys") not found
since Global Release is seemingly (partially?) working according to #8848 , maybe Cygames doesn't want to run on the Linux for Japan peoples :(
Reproduction
Open the game in Steam.

Did you try GE 10.3 as reported in #8848 ?
rinsuki commentedon Jul 1, 2025
I didn't tried it, but I don't think GE 10.3 would help me, since in JP release, the game will not even open any window, while #8848 (global release) says at least window will open and can see Cygames logo.

Tried

full log without any modifications
steam-3564400.log
The game window doesn't show up and it just crashes.
after asking a friend (they're on windows 11) to send their
WdfLdr.sys(and placing it indrive_c/windows/system32/drivers/), it also began to ask forWppRecorder.sysafter adding
WppRecorder.sys(into the same folder asWdfLdr.sys) it stopped giving the above errors however the game still crashes.steam-3564400.log - log with the above .sys files
there are also some other errors though:
(with the
WdfLdr.sysandWppRecorder.sysadded)(without adding any .sys files)
The global release doesn't have any logs related to WdfLdr.sys, here are the errors global release has despite launching just fine:
(global release log for comparison)
steam-3224770.log
Those who want to reproduce but are not in japan will need to make a new steam account with japanese vpn, otherwise you won't be able to download the game. If you can't find the game in steam just try to open it through the browser (you will still need to use japanese vpn).
The global release launches just fine for me (haven't tried to fully play it but it at least launches and I'm able to download the game content).
Edit:
I have fully updated my system and the game still crashes.
Linux: 6.15.4-arch2-1

Temporary workaround - Use at your own risk:
<Link removed by moderator>It has worked for me and I'm not responsible if you will get banned or if your computer explodes ๐
Launches just fine under GE-Proton10-8

Hello @justvam, the workaround you posted is legally problematic and has been removed.
yumio7 commentedon Sep 11, 2025
Is there still no workaround for this? Running into the same issue with various proton versions.
