Double Commander not working after fresh install of CachyOS

[gittus]

Hello,

because an update crashed my old system, I made a fresh installation of CachyOS (v20260308). Here, one of the first installations was DoubleCommander QT6 (v1.2.4-2). But after trying to start doublecmd, I got the error:

❯ doublecmd

SystemLocale de_DE
SystemLanguage de

  Sender=EAccessViolation
  Exception=Access violation
  Stack trace:

This happen to QT6 as well as QT5. I can run it successfully as root.

❯ pacman -Qi cachyos-ananicy-rules

Installiert von : Nichts
Name : cachyos-ananicy-rules
Version : 1:1.1.31-1

P.S. These trick with /etc/ananicy.d/99-systemd.rules does not work.

I use doublecmd-qt6 on Cachyos, which crashed with the message mentioned after an update. The following changes worked for me:
In the /etc/ananicy/00-default/DEs-and-WMs/ directory, I changed the types 'LowLatency_RT' and ‘BG_CPUIO’ to 'System' in the files lightdm.rules, sddm.rules, and gdm.rules (as they were before changes, such as cd1e889 for example).
