@kisak-valve I tried it with Experimental Proton and it's open infinitely with the black screen and the game pointer does not appear, from the logs is it possible to know if it is a problem that there is already some work in progress?, is there anything else i can do?

I'm guessing that we're seeing https://bugs.winehq.org/show_bug.cgi?id=44985 here.
Maybe try setting the game's launch options to WINEDLLOVERRIDES=libglesv2=d %command% and see if that works around the issue?
unfortunately have the same behavior :(

I want to test this solution, would it be possible to install corefonts in proton?
I installed protontricks and ran the command protontricks 1623660 corefonts, after that I tested without and with the WINEDLLOVERRIDES=libglesv2=d %command% but it still has the same problem
I tried this solution by replacing the files provided, it doesn't work.

I tried running with Proton-7.0rc2-GE-1 and the problem with GStreamer was fixed, when opening the game the video is displayed correctly with the audio but after that the game close

@M4rQu1Nh0S posted on 2022-10-22T19:50:39:
The game crashes with Proton running as Windows 10 Mode. with error in log:
Backtrace: =>0 0x000000025d7419eb DwmIsCompositionEnabled+0x5b() in dwmapi (0x000000000335c050) 0x000000025d7419eb dwmapi+0x19eb: movl\t%eax,(%rbx)
But running the game with Proton as Windows XP work, but chromium embedded framework (CEF) not work in Windows XP mode and i can't login.
Install the game from official launcher (https://live-dl.mir4global.com/global-launcher/Mir4Launcher_Install.exe)
Open the launcher and execute game 1.
MIR4 steam version freezes after some seconds after open the game.
Fixing the issue DwmIsCompositionEnabled can at last makes the MIR4 funtional.
