[BUG] Proton/UMU-Launcher deadlocks indefinitely at "wineserver: NTSync up and running!"

[zapzap-ske]

Pre-flight checklist

• I have searched existing issues and this is not a duplicate.
• I have read the Contributing Guidelines.
• I have verified the issue is reproducible with the latest available CachyOS kernel.
• I have tried to reproduce the issue on Arch Linux's linux kernel.

Upstream / vanilla kernel check

I have not tested with a vanilla/upstream kernel

Kernel variant

linux-cachyos (EEVDF, Clang)

System information (cachyos-bugreport.sh)

See attached log file below.

Manual system information (if cachyos-bugreport.sh is unavailable)

Bug description

All Wine/Proton compatibility frontends (including Bottles, Lutris, and Faugus Launcher) are completely unable to launch Windows games on my system. Regardless of the launcher or the runner used, games consistently experience either an instant silent crash or an indefinite deadlock during startup.

When debugging through the terminal, the process completely freezes right after initializing NTSync (wineserver: NTSync up and running!) and hangs forever until manually terminated via Ctrl + C. This identical behavior across multiple independent wrappers strongly indicates a systemic compatibility issue between the compatibility layer, the CachyOS kernel features (like NTSync), and the graphics stack.

cachyos-bugreport.log

Steps to reproduce

1. Install any non-Steam compatibility tool (Bottles, Lutris, or Faugus Launcher) from the CachyOS/Arch repositories.
2. Add a Windows game executable (.exe) to the launcher.
3. Attempt to launch the game using any available runner (such as Proton-CachyOS, UMU-Proton, or standard Wine-Staging).
4. Observe that the game window never appears, resulting in either an immediate silent crash or an infinite deadlock at the terminal level.

Expected behavior

Normally under similar test, the game would launch out of the box, this has been tested on Fedora and Mint Linux

Actual behavior

The game window never appears, it goes silent, crash without producing any error whatsoever.

Are you sure this is a kernel issue?

Oh man, I've been bashing my head against a wall for the better part of 24 hours trying to figure this out.
Everything comes back to the Node.js changes with 7.1.3-1

I've tried changing runners, changing from Lutris to Steam to Faugus, completely reinstalling, modifying the Windows registry on wine to ensure it has my time zone. Always end up in the same place - Nt and something to do with Node.js which I saw was changed in the new update.

I even nuked my entire network configuration to stock, which I now get to have fun trying to restore.

The ONLY thing that has worked was running my CachyOS LiveUSB which is linux-cachyos 6.19.10-1 ... fortunately I have enough RAM to get that working up to a point I could confirm the issue lol.

[Urmumm420]

The recent update to 7.1.3-1 has an update to tzdata which does not change when downgrading or trying LTS.
The hidden error

0470:fixme:ntdll:find_reg_tz_info Can't find matching timezone information in the registry
     for bias 420, std (d/m/y): 1/11/2026, dlt (d/m/y): 8/03/2026
0470:err:seh:NtRaiseException Unhandled exception code c0000409 flags 1 addr 0x1408a63b5

I was able to FINALLY AFTER way too long and burning through my claude limit 4 times, fix the issue.
This was my test:

TZ=UTC PROTON_NO_NTSYNC=1 PROTONPATH=GE-Proton10-34 GAMEID=umu-default \
  umu-run "/home/admin/Games/Ascension/drive_c/Program Files/Ascension Launcher/Ascension Launcher.exe" --no-sandbox

A temporary and quick fix for testing this would be to go into Configure > System Options > Environment Variables > Add
For the Key Field enter TZ and for the value enter UTC

If this fixes it for you, it then becomes a Wine or GE-Proton issue that they have to do on their end.
