It seems to add --no-sandbox flag can temporarily workaround the issue.

I too am getting this exact same output on console when launching the AppImage. It appears to be related to a problem similar to this Launchpad bug report indicating conflict between Electron 14 and a Canonical-provided libc ... Their build is contemporaneous to your Lepton 1.10.0 build (circa summer of 2021).
