Did you clone the repository recursively? Also experimental builds are available in this repository if you just want to check the new version: https://github.com/hexomancer/sioyek/releases/tag/v0.31.376

Hello, I cannot know how to run AppImage, this is what I see, but program is not opening:

Looks like there is an instance of sioyek already running. Make sure to close all the instances (maybe restart the system) and try again. If you want to launch a new window, you can pass the --new-window option.

There was some flash like that window shall open, but did not open. Then process remains hanging.

Attempt with another package:

Is AppImage supposed to be self contained?
