Pencil does not start on manjaro

[astrofrite]

• Operating system: Manjaro 21.2.6
• Pencil version: 3.1.0-7

When I launch pencil, it just display a white background with the logo blinking, and nothing else, if i launch it via command line, it outputs this :

useHWAConfig:  undefined
Hardware acceleration disabled for Linux.
[6462:0524/141911.986922:ERROR:sandbox_linux.cc(377)] InitializeSandbox() called with multiple threads in process gpu-process.
Background web-printer started.
Shortcut main service started.
(node:6431) ProtocolDeprecateCallback: The callback argument of protocol module APIs is no longer needed.

I'v seen 1 issue like mine, i tried to change in the /usr/share/applications/pencil.desktop the Exec="/usr/bin/pencil.sh" but it does nothing. When I try to launch it with electron, it outputs this error :

App threw an error during load

I'm new with manjaro so maybe it's an issue with how I installed it.

There is a discussion about this issue on AUR. Running pencil from electron11 worked for me well.

After installation just run electron11 /usr/lib/pencil/

The pencil 3.1.0-7 was worked for me in Manjaro using electron11 /usr/lib/pencil/, but currently not work. Actually I using pencil-git from AUR that work without problems, and, is not necessary the command using electron11. Other alternatives:

• Install pencil-snap-demo 3.0.4 from Snap but the UI is a little different.
• Download and install in opt/ folder the installer from here. And run with /opt/pencil-3.1.0/pencil
