Update on this issue:

It seems that this happens because I’m a developer, and I have NODE_ENV=development set globally. If I launch the AppImage like this: NODE_ENV=production ./Plexamp-3.4.3.AppImage, I don’t have that crash anymore. However, there seems to be another issue, this time with glibc.

Here is the new stacktrace:

Fontconfig warning: "/usr/share/fontconfig/conf.avail/05-reset-dirs-sample.conf", line 6: unknown element "reset-dirs"

I’m on the latest Fedora so I have a recent glibc, that seems to cause a problem with Chromium/Electron according to this GitHub issue for RStudio: syscall 0230 error on (arch)linux · Issue #6379 · rstudio/rstudio · GitHub

Update #2:

I have managed to make it run on my system, using the Flatpak version, here: Flathub—An app store and build service for Linux

Although I still have to manually set the NODE_ENV variable to production, or else the app doesn’t start because of the crash ENOENT: no such file or directory, open '/dev-app-update.yml'.

So, to make it work, I run: NODE_ENV=production flatpak run com.plexamp.Plexamp.

I hope this may help other users with the same problem!
