Double Commander doesn't start after system update.

Version

Double Commander
version: 1.2.4

Description

I'm using the latest version of Double Commander, from the AUR (CachyOS Linux) and the .appimage from the Releases section here on Github.

If I run the Double Commander appimage from the Terminal, this is what I get:

SystemLocale en_US
SystemLanguage en
SystemEncoding UTF-8
DefaultSystemCodePage 65001
DefaultFileSystemCodePage 65001
DefaultRTLFileSystemCodePage 65001
TServerListnerThread.Destroy
[FORMS.PP] ExceptionOccurred 
  Sender=EAccessViolation
  Exception=Access violation
  Stack trace:
  $00000000005BDEF8
[FORMS.PP] ExceptionOccurred

Normally, I can guess if there's a dependency issue or something, but this error is way too abstract for me to understand... Any tips?

Thank you in advance.

Thanks for responding (although the response wasn't the most verbose)...

Indeed when I launch it as root, Double Commander opens normally... The question is:

Is there any explanation for this or a solution/workaround?

Execute DC from console, after crash execute command stat /tmp/doublecmd-$UID and copy output here.

I get a "No such file or directory" error.

It might not be helpful, but I'm running LXQt Wayland on CachyOS.

So DC cannot create this directory. Looks like a problem with /tmp directory permissions.

I haven't make any change to the /tmp folder permissions in my CachyOS system since installing it back in december... Once again, anything I can do to get the information you need?

at the end of the day it seems like a common pattern for both issues is that this happens after an update and that the distro is CachyOS (dont see a similar issue on my arch btw). can you check if your user has access to /tmp or how mktemp behaves for example

Also try this command mkdir -m 0700 /tmp/doublecmd-$UID. Does it work? And show output of this command stat /tmp.

I have the same problem after updating, it seems to be an issue with ananicy-cpp. I fixed doublecmd not launching by creating this file, and then rebooting:

sudo nano /etc/ananicy.d/99-systemd.rules
[
{ “name”: “systemd”, “type”: “Service”, “nice”: 0, “latency_nice”: 0 }
]

It makes the folder "doublecmd-1000" in the /tmp folder without any problem.

The output of stat /tmp is:
