Sorry to bother you again but It worked fine on my laptop but not on my main PC. It should in theory be the same installation with similar packaged. For some reason web-greeter works just fine.

This time seems to be an Electron.js error. So, I have to ask: does this also happen on a desktop environment?

Also, try to set this line:

Exec=env ELECTRON_ENABLE_LOGGING=true ELECTRON_DEBUG_NOTIFICATIONS=true ELECTRON_ENABLE_STACK_DUMPING=true nody-greeter

... inside the xgreeter file (/usr/share/xgreeters/nody-greeter.desktop) and restart lightdm just to catch the possible electron.js errors inside /var/log/lightdm/seat0-greeter.log. According to this reddit post, it could be a missing file in the nody-greeter install directory.

Furthermore, check if the owner is set to root in /opt/nody-greeter directory.

I can't reproduce this anymore so you can close this if you want
