    this issue occured after login :(

    SBIE2103 indicates that a sandboxed program has requested to start a driver, and that the request was denied.
    Which driver is it? The exact name should be reported in the message.

    However, it looks like it was added a new Client anticheat without a clear mention on the 11.10 patch notes.

    SBIE2103 indicates that a sandboxed program has requested to start a driver, and that the request was denied.
    Which driver is it? The exact name should be reported in the message.

    However, it looks like it was added a new Client anticheat without a clear mention on the 11.10 patch notes.

    it try to load two drivers named "ace-base" and "ace-game", which should be TenProtect(Tencent's anticheat) as I know.
    But these driver already in previous version of this game, and the game can be played really well even with failed driver loads and some game crash reporter pops up.

    So I assume this is some sort of electron(chromium?) related issue and opened this issue :D

    SGuard64.exe (11864): SBIE2103 Denied attempt to load system driver 'ace-game [Easy] (StartService)'

    The reported messages. 👆

    So, Sandboxie could not fake a "system driver" loading right now?

    In order to take a log with Plus, you need to enable 'Trace Log' tab by opening 'Options' menu -> 'Trace Logging'.
    Once enabled, you can reproduce your issue.
    After reproducing it, just right click -> 'Copy Panel' to copy the full log and post it here:

    I am getting this:
    Trace Logging.txt

    This line is before the first WilError you've got when you were running Client.exe:
    Client.exe (15544, 13368) - 00:34:32.072 Ipc \Sessions\1\BaseNamedObjects\TenProtect3_Share_Data_15544

    As suggestion, you may apply ClosedIpcPath=\Sessions\*\BaseNamedObjects\TenProtect3_* to your sandbox and try again. If it didn't work, replace ClosedIpcPath with OpenIpcPath and try again.

    In case of failure, you could try the same with other Ipc(s) references or see also Sandboxie Trace if you need more debug output with IpcTrace=ad or IpcTrace=* (A and D mean allowed+denied access, * means log everything). In case you notice a perfomance decrease, that's expected. On the Plus UI, you can find these options in Sandbox options -> Advanced Options -> Tracing tab.

    Additionally, you may want to open/close Pipe paths or CLSIDs (COM classes), so If you need a brief summary of the various Resource Access settings: List of Resource Access Settings

    Has anyone successfully entered?
    I tried to find the line before the first WilError and apply some paths to the sandbox options.
    Unfortunately it didn't work.

    The original author of this issue already stated here that these drivers were already blocked in previous version of this game, and that the game could be played really well even with failed driver loads and some game crash reporter.

    Unfortunately I have nothing more, except debugging this issue and open/close Ipc(s) further as explained above.
    Additionally, you may want to open/close Pipe paths or CLSIDs (COM classes): List of Resource Access Settings

    I tried

    OpenIpcPath=\Sessions\*\BaseNamedObjects\__COND*
    OpenIpcPath=\Sessions\*\BaseNamedObjects\__IPC*
    

    and even

    OpenIpcPath=\*
    OpenIpcPath=\Sessions\*\BaseNamedObjects\__COND*
    OpenIpcPath=\Sessions\*\BaseNamedObjects\__IPC*
    

    according to LeagueClientUxRender.exe's log before it crash

    but still not work :(

    with IpcTrace=* enabled, log buffer seems be flooded
    I'll try some other tracing configuration later

    I also found some libcef crash memdump file generated by LeagueClientUxRender.exe, I downloaded the same version pdb symbol(91.1.22+gc67b5dd+chromium-91.0.4472.124_windows32), but failed to load pdb for the memdump file. I'm not really famillar with win32 things :(

    BTW I suddenly realized when the "game crash repoters" pops up in previous version of this game, is exactly at the same time as this black window appears. So I think game devs collected crash reports, decieded to ignore the crash and paint it all black :D

    Trying to find some workaround but got no luck, both of these are not work(or I did it wrong):

  • patch libcef.dll to enable --disable-gpu
  • hook CreateProcessW CreateProcessA to add --disable-gpu command line for LeagureClientUxRender.exe
  • I also tried League of Legends North America version
    which is operating by Riot Games, no TenProtect included
    and got excactly same result.

    So I think this is not anti-cheat related problem

    League of Legends is correctly running with latest version.

    Thanks!

    https://github.com/sandboxie-plus/Sandboxie/releases/tag/1.0.8 League of Legends is correctly running with latest version.

    Thanks for informing, I did more tests:
    Plus x64 0.9.8d: not work
    Plus x64 1.0.2: not work
    Plus x64 1.0.3: works
    Plus x64 1.0.8: works

    since Chromium HW acceleration issue is resolved in v1.0.3, I think it's related.
    huge thanks to developers actively maintaining!!

    NOTICE: Tencent will ban your account for a month if you run LOL in sandbox for "game client modification"

    Haven't experience it yet, i didn't play it within one or two week, version updated?
