It seems to be the same problem as https://github.com/ollm/OpenComic/issues/282#issuecomment-2424103294, it only happens on Ubuntu 22.04 or below, or in this case because the snap package is based on Ubuntu 20.04 (core20).

I will try to see if it is possible to change the snap base to core24 to solve this problem.

In the meantime you can use the deb package, which should not have this problem.

Waiting for https://github.com/electron-userland/electron-builder/pull/8549, electron-builder is not yet compatible with core24

For now, you will have to use the deb package or run this before running the snap package via the terminal.

Using the deb package worked, thank you for the great support.

After installing using dpkg -i opencomic_1.4.1_amd64.deb, I also had to chmod after checking syslog: The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /opt/OpenComic/chrome-sandbox is owned by root and has mode 4755.

This is another problem with electron in linux that has not been solved yet https://github.com/electron/electron/issues/42510 and https://github.com/electron/electron/issues/41066

Although it seems that this will be fixed when electron-builder v26 is released https://github.com/electron-userland/electron-builder/issues/8635 and https://github.com/electron-userland/electron-builder/pull/8636
